The values of r and w will be 50 and 140 degrees.
What is the Exterior Angle of a Triangle Property?
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
From the Exterior Angle of a Triangle Property;
38° + 103° = w
w = 140°
Let x be the exterior angle so that
x = r + 90°
Similarly,
By vertically opposite angle;
w = x
So, x = r + 90°
140 = r + 90°
r = 140 - 90
r = 50
Hence, the values of r and w will be 50 and 140 degrees.
