Question

Can someone please explain The measure of angle A to the nearest tenth of a degree is:

Answer 1

Answer:

A =19.5

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin A= opp/ hyp

sin A = 3/9

Take the inverse sin of each side

sin ^-1 sin A = sin ^-1 (3/9)

A =19.47122063

To the nearest  tenth of a degree

A =19.5

Answer 2

Answer:

19

Step-by-step explanation:

inverse sin (1/3) = 19.47122060852
