Question

Find the values of the angles a, b and c in each of the following:​

Answer 1

Answer:

GIVEN IN EXPLANATION

Step-by-step explanation:

A) a=120

   supplementary angles

   b=60

   opposite angles

   c=120

   opposite angle of ∠a

B) a=115

   as 180°=50+15+a

   b=130

   as it is supplement of 50

   c=50

   as it opposite to 50

Answer 2

Answer:

In first question b is 69

c is 21

d is21

Step-by-step explanation:

b is 69 because a and b are vertically opposite angles

After adding 69+69 =138

We got 138 as the sum

Total is 180. Subtract 180-138=42

Now divide 42/2

( a, c are too vertically opposite angles)

a=c=21
