Question

A 7-foot pole casts a shadow of 4 feet. how tall is a tree with a shadow of 13 feet?

Answer 1

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
