Question

Work out the size of angle x.

Answer 1

66°

Explanation:

Since the sum off all the angles of a triangle is 180°,

x + 79° + 35° = 180°

x + 114° = 180°

x = 180° - 114° = 66°

Therefore, x = 66°

Answer 2

x = 66

Explanation:

All triangle angles add up to 180 so:

x + 79 + 35 = 180

x + 114 = 180

x = 180 - 114

x = 66
