Is an obtuse triangle. given that = 20, the measure of = 30°, and the measure of = 45°, which of the expressions listed would be used to find how long is? (note: for , where a, b, and c are the lengths of the sides opposite , , and , respectively, .)

answer:

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
