Question

What is sin B as a fraction

Answer 1

SinB = 8/17

Explanation:

sinB = Opposite/Hypotenuse

Here we have to find the opposite side using the Pythagorean theorem.

AB^2 = AC^2 + BC^2

17^2 = AC^2 + 15^2

AC^2 = 17^2 - 15^2

AC^2 = 289-225

AC^2 = 64

Taking the square root on both sides, we get

AC = 8

Opposite side = 8

SinB = 8/17
