Answer:

measure of angle YVZ=56°

Step-by-step explanation:

angle WVY and angle YVZ form a right angle, meaning they add to 90 degrees.

We can make an equation out of this:

2x+3x+5=90

solve for x

5x+5=90

5x=85

x=17

substitute x back into the expression for angle YVZ because that's the measure we're looking for

angle YVZ=3(17)+5=56

Can someone please calculate the length ?

<h3>Answer:  11/20</h3>

=====================================================

Work Shown:

x = unknown horizontal length

1/5 = 0.2

Perimeter = 2*(width + length)

P = 2*(0.2 + x)

P = 0.4 + 2x

Set this equal to the given perimeter of 1 & 1/2 = 1.5 and solve for x

0.4 + 2x = 1.5

2x = 1.5-0.4

2x = 1.1

x = (1.1)/2

x = 0.55

x = 55/100

x = (5*11)/(5*20)

x = 11/20
