Angle rst measures 80 degrees. ray su bisects the angle. what is the measure of the two smaller angles

The measure of the two smaller angles i.e ∠RSU = ∠UST = 40° .

Step-by-step explanation:

As given

∠RST measures 80 degrees.

Ray SU bisects the angle.

Divided anything in two equal part is called bisect .

i.e SU bisect the ∠RST into two equal parts .

As the diagram is given below.

Thus

∠RSU = ∠UST = 40°

Therefore the measure of the two smaller angles i.e ∠RSU = ∠UST = 40° .
