Question

Calculate the magnitude of the angles as required.​

Answer 1

Answer:

angle B = 180-120 = 60

angle C = 180-130 = 50

sum of all angles of a triangle = 180

angle A = 180-(angle B + angle C)

angle A = 180-(60+50)

angle A= 180-110 = 70

So angle A is 70°

Answer 2

Answer:

ANGLE A = x

ANGLE B=120

ANGLE C=130

Total of all sides=180

x+120+130= 180

x+250= 180

x=250-180

x=70
