Answer:
C
Step-by-step explanation:
first you need to memorize
SOH CAH TOA
IT means
Sine =opposite/hipotenuse
Cosine = adjecent/hipotenuse
tangent = opposite/adjecent
in this case, we need to find sine
so it's SOH
opposite of theta Θ is 15
and it's hipotenuse , we don't know yet. so need to find it by using Pythagorean theorem
let it be x
x =√ 15²+ 8²
=√ 225+ 64
=√289
= 17
so the answer is 15/17
