Question

In the given figure side BC of triangle ABC is produced to D if angle ACD is equal to 128 degree and angle abc is equal to 43 degree find angle BAC and acb​

Answer 1

Answer:

BAC = 85° , ACB = 52°

Step-by-step explanation:

ABC = 43°

ACB + ACD = 180° --------- ( angle in linear

pair )

ACB + 128° = 180°

ACB = 180° - 128°

ACB = 52°

ABC + ACB + BAC = 180° ------- ( measure of

all angles

of a triangle is

180° )

43° + 52° + BAC = 180°

95° + BAC = 180°

BAC = 180° - 95°

BAC = 85°
