What is the measure of ∠RST ?
Marysya12 [62]
Remember that all the interior angles of a triangle add up to 180°.

The picture tells us two of the angles, \angle R which is 40° and \angle T which is also 40°.

Subtract the measurement of these two angles from 180° to find the measure of the third angle, \angle RST:
180° - 40° - 40° = 100°.

The measure of angle RST is 100°.

-------

Answer: 100°
