Question

In a right triangle sinA=3/4 and c=17.Find a and b.

Answer 1

If sin A = 3 / 4, one side is 3 and hypotenuse is 4.
Let other side = x
4² = 3² + x²
x² = 7
x = √7
Sides are √7, 3 and 4

Answer 2

remember sin= opposite side length over hypotenuse length. Assuming c is the hypotenuse (that's how most people write it) that means that 3/4, or .75=the length of the opposite side (A)/17. Multiply both sides by 17 and u get 12.75. u can use the pythagorean theorem or more trig to get b.
