**Question from Anya**

Course: Geometry

Chapter/Lesson/Problem11 test7b

Issue: I’m supposed to find Angle APM. To find the angle, I used tan APM=20/70, which gives 15.9 degrees. The solutions manual used sin APM=20/70, which gives 16.6 degrees. Sine is opposite/hypotenuse. However, it seems to me that the given measurements of the problem are opposite side (20) to the adjacent side (70). Which is correct? Thank you!

Yes, you are correct. That should be tangent as you stated.

tan(APM) = 20/70
