Question

7. Given & right triangle ABC, with

Angle C being the right angle,
segment AC = 3, segment BC = 4,
and segment AB = 5. Find the ratio
of sin A. *

Answer 1

4/5, or 0.8.

Explanation:

Since sin is equal to opposite over hypotenuse, and the opposite of side A is BC which equals 4 and the hypotenuse is 5, we then get BC/AB, which is thus, 4/5.
