The measure of angle STV is 80°.
The measure of angle STW is 35°.
The measure of angle WTV is x°.
Find the value of x.
To find the value of x, we need to use the fact that the sum of the angles in a triangle is 180 degrees.
We know that angle STV is 80 degrees and angle STW is 35 degrees. So, the sum of these two angles is 80 + 35 = 115 degrees.
Since the sum of the angles in a triangle is 180 degrees, we can subtract the sum of the two given angles from 180 to find the measure of angle WTV.
180 - 115 = 65
Therefore, the value of x is 65 degrees.
