Question

Plz help me on this one

Answer 1

I can’t see all the answer choices.

Answer 2

The sine of the angle = the length of the opposite side. the length of the hypotenuse.

The legnth of the Hypotenuse here is 29. However, because the question is "find sin(a)," then the answer should be "20/29".

Sorry if this is unconvientiant. : )

~Hope I helped
