Question

find the values of a b and c show steps
pls very urgent​

Answer 1

Answer:

b-78

c-60

Step-by-step explanation:

c is 60 bcoz 180-120=160 and the angle beside c is of 160

they both together make 180 That is why we did 180-120=60 (angle made by a straight line is 180)

therefore c is 60

To find the value of b

Value of the sum of angles of a triangle is 180

Two are 42 (given) and 60 (value of c) = 42+60=102

To find b (third angle) we will subtract the sum from the total i. e. 180-102=78
