Question

Find x.
Please explain how you found the answer.

Answer 1

Answer:

7. (i) Total angle = 360°

Given angles = 130° and 110°

130 + 110 + x = 360

240 + x = 360

x = 360 - 240

x = 120°

(ii) Total angle = 360°

Given angles = 282 and 33

282 + 33 + x = 360

315 + x = 360

x = 360 - 315

x = 45°

(iii) Total angle of a straight line = 180°

Given angles = 45,20 and 75

45 + 20 + 75 + x = 180

140 + x = 180

x = 40°
