Question

please solve the above equation​

Answer 1

Answer:

15. a) Angle a = 30

        Angle b = 100

        Angle c = 60

15. b) Since the angles do not add up to 90 degree, they are not complimentary.

Step-by-step explanation:

Angle B need to be obtuse

Angle C is = 180- (70 + 50) = 60

Angle A is half of Angle C = 30

Angle B = 100
