Question

Find side AC and round your answer to the nearest hundredth, help please.

Answer 1

Explanation:

Side AC is the side opposite the reference angle of 70 degrees while side BC is the side adjacent to the reference angle. AB is the hypotenuse since it is across from (or opposite) the right angle. The trig ratio that uses the sides opposite from and adjacent to the reference angle is the tangent. Setting up to solve for AC:

`tan(70)=(?)/(3)` and

3tan(70) = ? so

? = 8.24
