Answer:
18°
Step-by-step explanation:
x + 140° + 22° = 180° { being sum of angles of triangle }
x + 162° = 180°
x = 180° - 162°
x = 18°
Hope it will help :)
What are the solutions to (3x - 2) (4x + 1) = 0?
9514 1404 393
Answer:
x = 2/3, -1/4
Step-by-step explanation:
The zero product rule tells you a product will be zero only if one or more factors is zero. The solutions to this equation are the values of x that make one or the other of the factors be zero.
3x -2 = 0
3x = 2
x = 2/3 . . . . makes the first factor zero
__
4x +1 = 0
4x = -1
x = -1/4 . . . . makes the second factor zero
__
The solutions are ...
x = 2/3 or x = -1/4

A farm has pigs and chickens on it. There are a total of 20 animals and
62 legs. How many of each animal are there?
Answer:
Your answer would be 11 pigs and 9 chickens
Step-by-step explanation:
X= Chickens
Y= Pigs
11 is the number of pigs
9 is the number of chickens
11*4
multiply your number of pigs by the number of legs the animal has.
9*2
multiply your number of chickens by the number of legs the animal has.
11*4=44
9*2=18
44+18=62
add the calcutions together
Prove that √sec²
Given:
Consider the given statement is
[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]
To prove:
The given statement.
Solution:
We have,
[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]
Taking LHS, we get
[tex]LHS=\sqrt{\sec^2\theta+\text{cosec}^2\theta}[/tex]
[tex]LHS=\sqrt{\dfrac{1}{\cos^2\theta}+\dfrac{1}{\sin^2\theta}}[/tex]
[tex]LHS=\sqrt{\dfrac{\sin^2\theta+\cos^2\theta}{\sin^2\theta\cos^2\theta}}[/tex]
[tex]LHS=\sqrt{\dfrac{1}{\sin^2\theta\cos^2\theta}}[/tex] [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]
[tex]LHS=\dfrac{1}{\sin\theta\cos\theta}[/tex]
[tex]LHS=\dfrac{\sin^2\theta+\cos^2\theta}{\sin\theta\cos\theta}[/tex] [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]
[tex]LHS=\dfrac{\sin^2\theta}{\sin\theta\cos\theta}+\dfrac{\cos^2\theta}{\sin\theta\cos\theta}[/tex]
[tex]LHS=\dfrac{\sin\theta}{\cos\theta}+\dfrac{\cos\theta}{\sin\theta}[/tex]
[tex]LHS=\tan \theta+\cot \theta[/tex]
[tex]LHS=RHS[/tex]
Hence proved.

market stall holder bought a variety of coloured 'hoodies to sell. Each hoodie costs the stall holder $20 and she intends to sell them to the public at a mark up of 65%
write the percentage mark up value as:
1) fraction in simplest form
2) decimal
Answer:
20 x 0.65 = 13
20 + 13 = 33

In an acute angled triangle ABC, S is any point on BC. Prove
AB+BC+CA >2AS
Answer:
step below
Step-by-step explanation:
sum of any 2 sides of triangle > third side
AB + BS > AS (1)
CA + CS > AS (2)
AB + (BS + CS) + CA > 2 AS (1)+(2)
AB+BC+CA > 2AS
ergei wants to prove that Triangle A B C is similar to Triangle F G H. On a coordinate plane, triangle A B C has points (1, 1), (3, 3), (3, 1). Triangle F G H has points (4, 4), (12, 12), (12, 4). Which would help him prove that? Check all that apply. Measure angles A and F to show they are congruent. Measure angles F and G to show they are congruent. Use the right angle marks to show that angles C and H are congruent. Use the grid or a ruler to show that A B = F G, B C = F G, and A C = F H. Use the grid or a ruler to show that StartFraction F G Over A B EndFraction = StartFraction G H Over B C EndFraction = StartFraction F H Over A C EndFraction.

HELPPPPPP I HAVE NO IDEA HOW TO DO THIS!!!!!!!
Answer:
3 down 2 right
Step-by-step explanation:
A is at Y = 1, A’ is at Y = 4
4-1 = 3
It moved up 3 units.
A is at X = 1, A’ is at x = -1
1 - -1 = 2
It moved to the left 2 units.

Find the value of x. If needed round to the nearest tenth (one decimal place)
Answer:
x = 8.7
Step-by-step explanation:
The triangles are congruent, which means that the sides are proportional to each other. Line DE and line BE are proportional to each other. This means that:
8 = 12
We can simplify this down to
2 = 3
Now that we have this proportion we can apply it to Lines AE and EC
2(13) = 3x
26 = 3x
8.67 = x
Therefore x is equal to 8.67 (or 8.7 rounded)
Check:
8/12 = 0.6667
8.6667/13 = 0.6667
Since both are the same, the answer is correct.
I hope this helps!!

Charles and Seth are building a ramp for Sasha and Samantha. The base of the triangle is 11ft and it's height is 5ft. How long is the diagonal of the ramp?
Answer: 12.1 ft
Step-by-step explanation:
A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.
c² = a² + b²
Where:
c = hypotenuse
a = base
b = Height
c² = 11² + 5²
c² = 121 + 25
c² = 146
c = √146
c = 12.1 ft

What is the volume of this figure?
Answer:
677600
Step-by-step explanation:
you just have to multiply all the numbers together.
Answer:
2700 ft^3
Step-by-step explanation:
You can split up the object into two 3-dimensional figures and add them up.
The formula for this problem would be:
(11x10x22)+(7x4x10)
Now you have to multiply the numbers in the parenthesis and you would get:
2420+280
Then you would simply add and have a final answer of 2700.
