I'm studying for the math section of the ACT and I can't remember how to solve this problem.
A right triangle has legs of length 25 sin theta feet and 25 cos theta feet for some angle theta that satisfies 0< theta< 90. What is the length, in feet, of the longest side of the triangle?
F. theta
G. 1
H. 5
J. 25
K. Cannot be determined from the given information
I know that the answer is J but I wasn't given an explanation. If someone could help me that would be great.
