Question

To the nearest degree, what is m_A? Explain

Answer 1

Answer:

$A= 53$

Step-by-step explanation:

Given

$BC = 9,6$

$AC = 7.2$

Required: Angle A

This is calculated using:

$tan\ A = \frac{Opposite}{Hypotenuse}$

From the attachment;

$Opposite = 9.6$

$Adjacent = 7.2$

So:

$tan A =\frac{9.6}{7.2}$

$tan A =1.333$

Take arctan of both sides

$A= tan^{-1}(1.333$

$A= 53$----- approximated
