Question

The bear moves closer, so Rick decides to go to the other side of the lake. Since there is a forest, he can only spotpoint A when angle C measures 50'. What trigonometric function would Rick
use to find AB if he knows the measure of BC ?

Answer 1

Answer:

Tangent

Step-by-step explanation:

Given

$\angle C = 50$

Function to calculate BC

If AB is known, BC is calculated as:

$\tan(C) = \frac{AB}{BC}$

Substitute d for AB and 50 for C

$\tan(50) = \frac{d}{BC}$

Make BC the subject

$BC = d * \tan(50)$

Hence, BC can be found using tangent
