Question

!!!!!!!!HELP PLEASE!!!!!!!!       In ΔSTU, SU = 18 and TU = 13. Find m∠T to the nearest tenth of a degree.

Answer 1

We can use a trig function to find the measure of angle T.

tan(T) = 18/13

Take the archtangent on both sides since we are searching for an angle.

arctan(tan T) = arctan(18/13)

T = 54.16°

The measure of angle T is 54.16°.
