pythagorean theorem A^2 + B^2 = C^2
C = 17 and B = 15

A^2 + 15^2 = 17^2
A^2 + 225 = 289
A^2 = 289 - 225
A^2 = 64
A = square root of 64
A = 8

First a lesson in internet safety -> never post something on a open site such as this with identifying information. Your name is on the paper.

I haven't reviewed trig yet so I'll leave it to others to help, Just one last comment though, Question 1 says to round to the nearest tenth - you have a decimal containing hundredths.
