Given:

Angle STV is a straight angle. The measure of angle WTV is 65°. The measure of angle STW is x°.

To find:

The value of x.

Solution:

Angle STV is a straight angle. So, the measure of angle STV is 180 degrees.


m\angle STV=180^\circ


m\angle STW+m\angle WTV=180^\circ

The measure of angle WTV is 65°. The measure of angle STW is x°.


x^\circ+65^\circ=180^\circ


x^\circ=180^\circ-65^\circ


x^\circ=115^\circ


x=115

Therefore, the value of x is 115.
