Answer:

$46.2^o$

Step-by-step explanation:

The correct question is

If b = 9 and c = 13, what is the measure of ∠A? (round to the nearest tenth of a degree)

The picture in the attached figure

we know that

In the right triangle ABC

$cos(A)=\frac{b}{c}$ ---> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(A)=\frac{9}{13}$

using a calculator

$A=cos^{-1}(\frac{9}{13})=46.2^o$
