Answer:
36 ft
Step-by-step 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: 36 ft
<u>Step-by-step explanation:</u>
Similar triangles means there is a constant proportion between the left legs, the base legs, and the hypotenuses.
Cross multiply: x(4) = 3(48)
solve for x: <u> ÷4 </u> <u> ÷4 </u>
x = 3(12)
= 36
