Question

A) Work out the size of angle x.

b) Give reasons for your answer.

Answer 1

75

Explanation:

180° - 105° = 75°. x = 75°

Answer 2

x = 75°

Explanation:

Angle x and the angle measure 105° are same-side exterior angles. Same-side exterior angles are supplementary. Supplementary angles are angles measures that add up to 180°. So 180° - 105° = 75°. x = 75°
