Answer:
45
Step-by-step explanation:
From the figure given, TV and RS are parallel.
Therefore, angle VTS and angle RST equal (Alternate angles)
Thus, angle VTS = angle RST = x
Angle T + angle S + angle R = 180° (sum of angles in a triangle)
2x + x + x = 180
4x = 180
Divide both sides by 4 to solve for x
x = 180/4
x = 45
The value of x in each case is 45
If we input 45 as a value of x in the angles in the triangle, the sum of what we have will give us 180°.
