As the triangle is similar angle don't change so 50+70=120 and the angle of a triangle total to 180 so 180-120=60
Answer:
60°
Step-by-step explanation:
As it is said that the triangles are similar so In the similar triangles corresponding angles are equal so
< A = 50°
<E = 70°
< B = < E = 70° { being corresponding angles of similar triangles }
Now
< A + <B + < C = 180° {Being sum of angles of triangle }
50° + 70° + < C = 180°
< C = 180° - 120°
< C = 60°
Hope it will help :)❤
You can model an arch at your school using the equation $y=-0.5\left(x+4\right)\left(x-4\right)$ , where $x$ and $y$ are measured in feet. The x-axis represents the ground. Find the width of the arch at ground level.
Answer:
8feet
Step-by-step explanation:
Given the equation that models the arch of a school expressed as;
[tex]$y=-0.5\left(x+4\right)\left(x-4\right)$[/tex]
If the x axis represents the ground;
At the ground level, x = 0
Substitute x = 0 into the equation to get y;
y = -0.5(0+4)(0-4)
y = -0.5(4)(-4)
y = -0.5 * -16
y = 8ft
Hence the y axis at the ground level is 8feet

What package is the Best Buy?
Answer: The answer is 8 lb for $18.80
That is the answer because you have to divide in order to see which is the best buy
You have to divide $4.98 by 2lb and you will get 2.49, divide $12.25 by 5lb which equals 2.45, divide $18.80 and you will get 2.35, divide $23.70 by 10lb and you will get 2.37. So therefore you answer is C.8lb for $18.80 because 2.35 is better than the other deals.

Una garrafa de aceite equivale a 5 botellas y 3 garrafas es igual a 7, las cuales suman 11 litros, ¿Cuál es las capacidad de una botella y una garrafa?
Respuesta:
Botella, B = 0.5
Jarra, C = 2,5
Explicación paso a paso:
Dejar :
Garrafa = C
Botella = B
C = 5B - - - - 1)
3 garrafas más 7 botellas = 11 litros
3C + 7B = 11
C = 5B
3 (5B) + 7B = 11
15B + 7B = 11
22B = 11
B = 11/22
B = 1/2 = 0,5
Sustituyendo B = 0.5 en 1)
C = 5B
C = 5 (0,5)
C = 2,5

The cost of the hiking trip this year is 2/3of the cost of last year's trip. This year's trip cost $32
1. Write an equation that represents the cost of last years trip.
2.What was the cost of last year's trip
Answer:
The equation is ( 32/2 ) × 3 = 48.
Step-by-step explanation:
In order to find the answer, we must find one third of last years trip. To do this, we can simply divide the cost of this year's trip by two, 32/2=16.
Now if we multiply this years trip by 3, 16×3=48, we can see that the total cost of last years trip was $48.
If we'd like to turn this into a equation, it looks like this:
( 32/2 ) × 3 = 48.

What is an expression?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.Many authors make a distinction between an expression and a formula, with the former designating a mathematical object and the latter a claim about such objects.Solution -The piece of rope is 1m long.
Carter divided the ropes into three equal parts by tying up the knot.
1 meter = 3 foot.
Therefore, divide 3 by 3.
[tex]\frac{3}{3} =1[/tex] foot.
Therefore, each section is 1 foot long.

Fred is making a wooden box in the shape of a right rectangular prism. The dimensions of the box are 12 inches by 4 1/4 inches by 4 1/4 inches. What is the volume of the wooden box?
Answer:
867/4 in3
Step-by-step explanation:
v= l*w*h= 12* 17/4* 17/4
= 51*17/4 = 867/4 in3
if my answer helps please mark as brainliest.
Answer:
[tex]V=216\frac{3}{4} in^{3}[/tex]
Step-by-step explanation:
The formula for volume of a rectangular prism is V = w × h × l, where
V represents the volume
w represents width
h represents height
l represents length
So, all we have to do to find volume is multiply these three values together, like this:
V = 12 × [tex]4\frac{1}{4}[/tex] × [tex]4\frac{1}{4}[/tex]
[tex]V=(12)(\frac{17}{4} )(\frac{17}{4} )[/tex]
Then we multiply all the numerators:
[tex]V =\frac{867}{4}[/tex]
[tex]V=216\frac{3}{4} in^{3}[/tex]
I NEED HELP WITH THIS one angle of a triangle measured 145 degrees. The other two angles are in a ratio of 2:3. what are the measures of those two angles?
Answer:
Step-by-step explanation:
A triangle has 180 degrees in total. One of the angles are 145 degrees, so we can subtract and get 35 degrees. Then, it says that the remaining angles are in a ratio 2:3. So, we would have:
[tex]2x:3x = 35 \\2x+3x = 35\\5x=35\\x=7[/tex]
Now that we know what x is, we can multiply that to our ratio:
[tex]2\cdot7=14 \text{ degrees for the first angle}\\3\cdot7=21 \text{ degrees for the second angle }[/tex]

Are the Triangle similar? Why or why not?
Answer:
No, they are not similar
Step-by-step explanation:
The three triangle angles should always add up to 180 degrees.
In the smaller triangle, one angle is 90 degrees, so the other 2 angles in that triangle will equal 90 when added.
In the bigger triangle, the 2 other angles are 60 & 70 degrees, amounting to 130 degrees. This means the last angle will be 50 degrees.
In the end, these two triangle are NOT similar because one has a right angle and the other doesn't.

Jarry is making a strawberry smoothie which measure is greatest the amount of milk cottage cheese or strawberry
Answer:
Milk
Step-by-step explanation:
The amount of milk, cottage cheese and strawberries used are given in the attached picture.
3/4 cup of milk
2/6 cup cottage cheese
8/12 cup strawberry
Converting the fractions to decimal :
3/4 cup of milk = 0.75
2/6 cup cottage cheese = 0.3333
8/12 cup strawberry = 0.66666
0.75 > 0.6666 > 0.3333
We can conclude that amount of milk is greatest, then strawberry and the least is cottage cheese.
