Answer:
B
Step-by-step explanation:
<u>This is a right triangle as shown by the right angle.</u>
- The side opposite the right angle is the hypotenuse, which is 9.
- The side opposite angle A is 3.
So we have the opposite of A and the hypotenuse.
The trigonometric ratio that relates opposite side to hypotenuse is SINE.
Since, we need angle A, is A, opposite side is 3, and hypotenuse is 9, we substitute:
<em>To solve for the angle, we use our calculator and find the inverse sin of :</em>
<em>Rounding to nearest tenth of a degree:</em>
B is the right choice.
