Question

use trig to determine the value of x for the right triangle. Round answer to nearest tenth. Show work and explain

Answer 1

15.4

Explanation

From the diagram, we are given;

Adjacent = 12

Hypotenuse=x

Angle of elevation =39°

Using the SOH CAH TOA identity

Cos 39 = 12/x

x = 12/cos39

x = 13/0.7771

x = 15.44

Hence the value of x to nearest tenth is 15.4
