Question

To the nearest degree, what is m_A? Explain

Answer 1

`A= 53`

Explanation:

Given

`BC = 9,6`

`AC = 7.2`

Required: Angle A

This is calculated using:

`tan\ A = (Opposite)/(Hypotenuse)`

From the attachment;

`Opposite = 9.6`

`Adjacent = 7.2`

So:

`tan A =(9.6)/(7.2)`

`tan A =1.333`

Take arctan of both sides

`A= tan^(-1)(1.333`

`A= 53`----- approximated
