Step-by-step explanation:
- length of pole = 7 foot (length )
- cast shadow = 4 feet ( base)
Hypotenus = AB^2 = AC^2+ BC^2
= 7^2 + 4^2
= 49 + 16
= √65 feet
= 8.06 feet
Now, shadow of tree = 13 feet
hypotenuse. = 8.06 feet
length = AB^2 = AC^2 + BC^2
8.06^2 = y^2 + 13^2
64.9636 = y^2 + 169
64.9636 - 196 = y^2
104.0364 = y^2
√104.0364 = y
10.199. = y
