The triangle is an isosceles triangle and it's external angle is 150°

=>The angles opp. to the equal sides are 30°

=>The third angle of triangle = 180°- (30°+30°)= 120°

=>The third angle = angle q (Because of the parallel lines)

=>angle q = C:-120°

Answer 2

Answer:

120°

Explanation:

180° - 150° = 30°

150° - 30°= 120°

there is no names given for the lines and angles so it is difficult to explain
