Question

Tell whether the angles are complementary or supplementary. Then find the value of x.

Answer 1

• The angles are complementary and the value of x is 5
• The angles are supplementary and the value of x is 20

Complements and supplements of angles.

The sum of complementary angles is 90 degrees while the sum of supplementary angles is 180 degrees,

7) This is a right angle, the sum of the angles will be complementary (sums up to 90)

65 + 5x = 90

5x = 90 - 65

5x = 25

x = 25/5

x = 5

8) Since the angles form a linear pair, hence the sum is supplementary,

2x + 6x + 20 = 180

8x = 180 - 20

8x = 160

x = 160/8

x = 20
