Use the diagram to answer the question. Triangle A B C. Segment B C measures 13. Segment A C measures 15. Angle B is a right angle.
What is the measure of ∠A?

Oh my, somebody seriously has to review the basic trig ratios to find that
sinA = 13/15
A = arcsin(13/15) = ....

on my calculator I did
13 ÷ 15 = ...
2ndF sin = ...

or I could have done
2ndF (13÷15) =
