Answer 1

36 ft

Explanation:

So the proportion of the big triangle is 48:4 or 12:1. So if the small triangle’s height is 3 feet, then 3*12 is 36 feet.

Answer 2

Answer: 36 ft

Explanation:

Similar triangles means there is a constant proportion between the left legs, the base legs, and the hypotenuses.

`(LeftLeg(large))/(LeftLeg(small))= (BaseLeg(large))/(BaseLeg(small))`

`(x)/(3)= (48)/(4)`

Cross multiply: x(4) = 3(48)

solve for x: ÷4 ÷4

x = 3(12)

= 36
