Answer 2

Answer:

(i) The sum of all angles of a triangle = 180°

45° + 30° + x = 180°

75° + x = 180°

x = 180°-75°

x= 105°

(ii) One angle is right angle = 90°

90° + 30° + x = 180°

120° + x = 180°

x = 180° - 120°

x = 60°

(iii) x is an exterior angle.

Exterior angle = sum of two opposite angles

x = 60° + 65°

x = 125°
