Question

Shadow A person casts the shadow shown. What is the approximate height of the person?

Answer 1

height of person ≈ 6 ft

Explanation:

using the tangent ratio in the right triangle.

let the height of the person be h , then

tan16° =
`(h)/(21)` ( multiply both sides by 21 )

21 × tan16° = h , then

h ≈ 6 ft ( to the nearest whole number )
