Question

Find the missing side round to the nearest tenth can someone please help me this is my last question

Answer 1

The question is related to trigonometric ratio rule .

In the given diagram, there is a right angle triangle, with adjacent =57, and the unknown side is y. Given angle measurement is 39 .

To find the measurement of y, we will use tan rule which is

$tan \Theta = \frac{opposite}{adjacent}$

$tan 39=\frac{y}{57}$

y = 57 tan 39 = 46.2
