Step-by-step explanation:
- The angles are complementary and the value of x is 5
- The angles are supplementary and the value of x is 20
<h3>Complements and supplements of angles.</h3>
The sum of complementary angles is 90 degrees while the s<u>um of supplementary angles is 180 degrees,</u>
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
