Find the missing side in the similar figures below
Lerok [7]

Answer:

a. 28.8

Step-by-step explanation:

Solve for x

\frac{x}{12} = \frac{60}{25}

Cross multiply

x*25 = 60*12

25x = 720

Divide both sides by 25

x = 28.8

1. A trapezoid has an area of 91 m2. The height of the trapezoid is 7 m and the measure of one base is twice the height. What is
Lynna [10]
The area of the trapezoid is given by:
 A = (1/2) * (b1 + b2) * (h)
 Where,
 b1, b2: bases of the trapezoid
 h: height
 Substituting values we have:
 91 = (1/2) * ((2 * 7) + b2) * (7)
 Rewriting we have:
 91 = (1/2) * (14 + b2) * (7)
 (2/7) * 91 = 14 + b2
 b2 = (2/7) * 91 - 14
 b2 = 12 m
 Answer:
 
The measure of the other base of the trapezoid is:
 
b2 = 12 m
