Answer:

use trigonmetric function (soh-cah-toa)

first: we have the given height so its represent as the opposite and the distance is the adjacesnt so we will going to use TOA

tangent52 =42/a

axtangent52=42

axtangent52/tangent52 = 42/tangent52

A =32.8139m

tangent2

Step-by-step explanation:

tangent27 =42/a

axtangent27=42

axtangent27/tangent27 = 42/tangent 27

a = 82.429m
