Hey I can help. Do u still need it?
Uh... What diagram? I cant understand what you are tryimng to ask if i dont even know where the diagram is. Just saying.
This is a right triangle, the measure of angle A is 90 degrees.
First thing to do I guess is finding B and C.
tan^-1 (7/12) = 30 degrees
tan^-1 (12/7) = 60 degrees
60 + 30 = 90
180 - 90 = 90. Therefore angle A = 90 degrees
