Question

What is sin B? 15/17 8/17 12/17 Not enough information

Answer 1

SinB = 8/17

The sin of an angle is equal to opposite/hypotenuse

Use Pythagorean’s Theorem to solve for the opposite side

$15^{2} +b^{2}=17^{2} \\225 + b^{2} =289\\b^{2} =64\\b=8$

The opposite side is equal to 8

So sinB = 8/17
