What is sinb ? express your answer as a fraction.

sin B = 8/17

Step-by-step explanation:

sin B can be expressed as the opposite over the hypotenuse in a right triangle.  But we don't know the opposite yet.  We can use the Pythagorean theorem to solve for it

a^2 + b^2 = c^2

15^2 +b^2 = 17^2

225+b^2 = 289

Subtract 225 on each side

225-225 +b^2 = 289-225

b^2 = 64

Take the square root of each side

b=8

The opposite side is 8

sin B = opp/hyp

sin B = 8/17

step-by-step explanation:

the answer is 0.3175 hope that you ^w^
