Question

Find the value of x if the measure of angle 1 = 11x - 9 and the measure of angle 5 = 7x + 9

Answer 1

Answer:

x = 10

Step-by-step explanation:

Lett angle 1 and angle 5 lie on the same straight line. This shows that they are supplementary

Hence;

<1 + <5 = 180

11x - 9 + 7x + 9  = 180

18x = 180

x = 180/18

x = 10

Hence the value of x is 10
