Thank you for the opportunity to help you with your question!

The good thing is, we are given the lengths of all three sides.

You are free to use any 3 of the trigonometric functions.

sin B = 8/17

cos B = 15/17

tan B = 8/15

I will use sin B = 8/17 to solve for angle B.   B = arcsin (8/17)  by taking the inverse of sine on both sides of the equation.

B = arcsin (0.47058823 ) = 28.07248693  degrees.

Therefore if we round this number, we get:  angle B = 28 degrees.

Choose Choice A.  28

Please let me know if you need any clarification. I'm always happy to answer your questions.

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
