If AC=10cm and CB=26cm, find BA.
If CB=16cm and AB=22cm, find CA.
please answer both
Answer:
BA = 36 cm
CA = 6 cm
Step-by-step explanation:
CB + AC = BA
26 + 10 = 36 cm
AB - CB = CA
22 - 16 = 6 cm
Twice the sum of Paloma's age and 15 is 106. How old is Paloma?
Answer: 121
Step-by-step explanation:
Paloma's age is 45.5 years
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
For given example,
Let 'm' be the age of Paloma.
Twice the sum of Paloma's age and 15 is 106.
We write above statement in equation form.
⇒ Twice the sum of Paloma's age and 15 is 106
⇒ 2m + 15 = 106
So, we get an equation,
2m + 15 = 106
We solve above equation to find the value of 'm' (Paloma's age)
⇒ 2m + 15 =106
⇒ 2m = 91
⇒ m = 91/2
⇒ m = 45.5 years
45.5 years means 45 years and 6 months
This means, Paloma age is 45 years and 6 months
Therefore, Paloma's age is 45.5 years.

[tex]3x + 2x + 90 = 180[/tex]
what is the value of x??
Answer:
18
Step-by-step explanation:
5x+90=180
5x=90
x=18
Can i get brainliest?
Hi there!
[tex]\large\boxed{x = 18}[/tex]
3x + 2x + 90 = 180
Begin by combining like terms:
5x + 90 = 180
Subtract 90 from both sides to isolate for x:
5x + 90 - 90 = 180 - 90
5x = 90
Divide both sides by 5 to further isolate:
5x/5 = 90/5
x = 18.

Answer:
║w║ = 6
Step-by-step explanation:
(c) The magnitude of w is computed the same way the magnitudes of the other vectors are computed. It is the root of the sum of the squares of the components.
║w║= ║<-6, 0>║ = √((-6)² +0²) = √36
║w║= 6
Calvin Butterball is lying on the ground and spots a hot air balloon at an angle of elevation of 28 The distance from Calvin to the hot air balloon is 850 feet. How high in the air is the balloon?
Answer
the distance between the posts is 1 mile
let x be the horizontal distance between the pole 1 and the ballon
Step-by-step explanation:
height of balloon = h
tan 24 = h/x
h = x tan 24
similarly
h= (x+1) tan 20
xtan 24 = (x+1) tan 20
Answer: approximately 399 feet
The more accurate value is 399.050828368008 feet, but this value is still approximate.
========================================================
Work Shown:
Refer to the diagram below.
To find x, we'll use the sine rule
sin(angle) = opposite/hypotenuse
sin(28) = x/850
850*sin(28) = x
x = 850*sin(28)
x = 399.050828368008 ...... make sure your calc is in degree mode
x = 399
I'm rounding to the nearest whole number since the given values (28 and 850) are also whole numbers. If your teacher provides other rounding instructions, then be sure to follow that.
The hot air balloon is approximately 399 feet off the ground.

The price of a calculator is Rs 3000 excluding 13% VAT in the shop A, while its price is Rs 3,277 including VAT in the shop B. Which shop is cheaper and by how much?
Answer:
Shop B is cheaper than shop A by ₹44.87.
Step-by-step explanation:
For shop A:
Amount of VAT = 13% of 3000 = ₹390
For shop B:
Let the price of the calculator excluding VAT be ₹x.
Therefore,
x + 13% of x = 3000
x + 0.13x = 3000
1.13x = 3000
x = 3000/1.13
x = 2,654.86726
x = ₹2654.87
Amount of VAT = 3000 - 2654.87
= ₹345.13
390 - 345.13 = ₹44.87
So, shop B is cheaper than shop A by ₹44.87.
Joshua has a ladder that is 14 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 13.8 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 78°. Will the ladder be safe at this height? Show your work and draw a diagram to support your answer.
Answer:
Step-by-step explanation:
sinθ = 13.8/14
θ = arcsin(13.8/14) = 80.3°
The ladder is not safe at that angle.
Jenny examined the 14 machine parts made in an hour at a factory. She found that 3 of the parts were broken. If this
pattern continues for the next four hours, Jenny wants to find how many parts the factory will make in four hours that are
NOT broken.
Drag and drop the responses into the boxes below to create the expression that Jenny needs to represent this situation.
Answer:
44 machine parts won't be broken.
Step-by-step explanation:
14 per hour
3 out of those 14 was broken
14 - 3 = 11 that will turn out, not broken
11 per hour
if we're going to work out 4 hours we need to multiply it by 4
11 × 4 =44
1 × 4 = 4
44 per hour that will not turn out broken because we disincluded the broken parts that will be there.

Explain how you can differentiate between a square, rhombus, and rectangle based on the angles formed by their diagonals.
Answer:
Quadrilateral just means "four sides"
(quad means four, lateral means side).
A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
Step-by-step explanation:
propertiesA quadrilateral has:
four sides (edges)
four vertices (corners)
interior angles that add to 360 degrees:
Quadrilateral Angles
Try drawing a quadrilateral, and measure the angles. They should add to 360°
Types of Quadrilaterals
There are special types of quadrilateral:
Types of Quadrilateral
Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. See below for more details.
Let us look at each type in turn:
The Rectangle
Rectangle
the little squares in each corner mean "right angle"
A rectangle is a four-sided shape where every angle is a right angle (90°).
Also opposite sides are parallel and of equal length.
The Square
Square
the little squares in each corner mean "right angle"
A square has equal sides (marked "s") and every angle is a right angle (90°)
Also opposite sides are parallel.
A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
The Rhombus
Rhombus
A rhombus is a four-sided shape where all sides have equal length (marked "s").
Also opposite sides are parallel and opposite angles are equal.
Rhombus Diagonals
Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.
A rhombus is sometimes called a rhomb or a diamond.
The Parallelogram
Parallelogram
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same).
NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
Example:
Square
A parallelogram with:
all sides equal and
angles "A" and "B" as right angles
is a square!
The Trapezoid (UK: Trapezium)
Trapezoid (or Trapezium) Trapezoid (or Trapezium)
Trapezoid
Isosceles Trapezoid
A trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel.
And a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides:
Trapezoid Trapezium
In the US: a pair of parallel sides NO parallel sides
In the UK: NO parallel sides a pair of parallel sides
(the US and UK definitions are swapped over!)
An Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles.
The Kite
The Kite
Hey, it looks like a kite (usually).
It has two pairs of sides:
Each pair is made of two equal-length sides that join up.
Also:
the angles where the two pairs meet are equal.
the diagonals, shown as dashed lines above, meet at a right angle.
one of the diagonals bisects (cuts equally in half) the other.
... and that's it for the special quadrilaterals.
Irregular Quadrilaterals
The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.
The "Family Tree" Chart
Quadrilateral definitions are inclusive.
Example: a square is also a rectangle.
So we include a square in the definition of a rectangle.
(We don't say "Having all 90° angles makes it a rectangle except when all sides are equal then it is a square.")
This may seem odd, as in daily life we think of a square as not being a rectangle ... but in mathematics it is.
Using the chart below we can answer such questions as:
Is a Square a type of Rectangle? (Yes)
Is a Rectangle a type of Kite? (No)
Quadrilateral Classification
Complex Quadrilaterals
Oh Yes! when two sides cross over, we call it a "Complex" or "Self-Intersecting" quadrilateral, like these:
Complex Quadrilaterals
They still have 4 sides, but two sides cross over.
Polygon
A quadrilateral is a polygon. In fact it is a 4-sided polygon, just like a triangle is a 3-sided polygon, a pentagon is a 5-sided polygon, and so on.
Play with Them
Now that you know the different types, you can play with the Interactive Quadrilaterals.
Other Names
A quadrilateral can sometimes be called:
a Quadrangle ("four angles"), so it sounds like "triangle"
a Tetragon ("four polygon"), so it sounds like "pentagon", "hexagon", etc.
