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
