Answer:
The angles are complementary
x is 55 degrees
Step-by-step explanation:
Complementary angles are angles that sums up to 90 degrees
Since a ray intersects two other rays forming a right angle, hence the sum of the two angles is 90degrees and this shows that the angles are complementary.
Given the two angles to be x and (x-20). Taking their sum and equating it to 90 degrees, we will have;
x + x - 20 = 90
2x - 20 = 90
2x = 90+20
2x = 110
x = 110/2
x = 55 degrees
Hence the value of x is 55degrees
