Find the largest side of △STU, given that m∠T=98°, m∠S=30°, and m∠U=52°.

SU

=======================================================

Explanation

Rule:  The longest side of any triangle is always opposite the largest angle.

Angle T = 98 is the largest angle, so the longest side is SU since it is opposite angle T.

Refer to the diagram below.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
