Question

I need help please I don't understand

Answer 1

57.2

Explanation:

This is a right triangle so we can use trig ratios.

We are asked to find a side when we know a angle adjacent to that side. And we are given a side opposite of that angle. We can use Tangent to find the side length.

`\tan(40) = (48)/(x)`

Take the reciprocal of both sides.

`(1)/( \tan( 40) ) ) = (x)/( 48)`

Multiply both sides by 48.

`x = (1)/( \tan(40) ) * 48`

`x = 57.2`
