Answer» A + B = 180 [sum of supplementary angles] 3x-3+2x+3 = 180 5x = 180 x = 36° angle A = 336 - 3 = 105° angle B = 236 + 3 = 75°

Solve all questions. Each sub-question carries two marks.Q. 8 A) ZA and ZB are supplementary angles. mZA (3x 3);mZB (2r 3)0. Find the value of x and hence find the measuresof ZA and ZB.

Answer»

A + B = 180 [sum of supplementary angles]

3x-3+2x+3 = 180

5x = 180

x = 36°

angle A = 3*36 - 3

= 105°

angle B = 2*36 + 3

= 75°
