Answer:

x = 6 cm

Step-by-step explanation:

Given ratio of sides of similar figures = a : b , then

ratio of areas = a² : b²

Here ratio of areas = 5 : 45 = 1 : 9 , so

ratio of sides = [tex]\sqrt{1}[/tex] : [tex]\sqrt{9}[/tex] = 1 : 3

Thus side of B is 3 times side of A

x = 3 × 2 = 6 cm

Find the value of x.

Answers

Answer:

x=77°

Step-by-step explanation:

All quadrilaterals' interior angles sum to 360°, so to solve one angle in the trapezoid, we can subtract the angles we have from 360.

So x=360-(60+128+95)=77°

x=77°

− x + 3 − ( x − 5 )

Distribute the Negative Sign:

= − x + 3 + − 1 ( x − 5 )

= − x + 3 + − 1x + ( − 1 ) ( − 5 )

= − x + 3 + − x + 5

In a problem like this, you have the see it as two separate problems before you can complete it. I’ll show work but I want to use words to maybe help you understand for the future. So split them apart to become (-x+3) as the first step and leave that alone for now. Then look at -(x-5). With the variable in place, you need to think of the subtraction sign as a negative integer and distribute it to the variables in the parentheses. The negative combines with the x to make a -x and the negative combines with the -5 to make a positive five. So now we have -x+5
After you complete that first part, you can pull the first part back and start to combine them. -x+3-x+5 becomes -2x+8.
Now here’s the work part.
(-x+3)-(x-5)
(-x+3) (-x+5)
-x (+) -x = -2x
3+5 = 8
-2x+8 is the final answer

The answer is y=180

Answer:

y = 180

Step-by-step explanation:

y = 300 - 5 (24)

*remember order of operations using PEMDAS: (parenthesis > exponents > multiplication/division > addition/subtraction)

solve parenthesis first:
