Question

Please help! The question is attached. And also I know the numbers on the triangle are blurry. The number on the long bottom of the triangle is 24, the one in the corner of the bottom of the triangle is 90 degrees, the side length is 18, and the diagonal angle is 26.

Answer 1

If the legs of the triangle are what you say, there is no correct answer.  The sin(θ) function is the ratio of the opposite side to the hypotenuse.  In this case that's 18/26.  Are you sure the opposite side length is not 10?  It kinda looks like a 10 and that would make choice B correct.
