Question

Classify the pair of angles. then find the value of x. (need help with 13 & 15!)

Answer 1

The value of x from the figures are 18 and 26 respectively

Vertical and complementary angles

13) From the diagram, the angles at the corner is 90 degrees. This shows that the sum of the angles is complementary (sum is 90 degrees)

3x + 2x = 90

5x = 90

x = 90/5

x = 18

15) Since the sum of angles on a straight line is supplementary, hence;

6x + x - 2 = 180

7x = 182

x = 182/7

x = 26

Hence the value of x from the figures are 18 and 26 respectively
