Question

in figure 3find the value of a,b and c.​

Answer 1

Answer:

B=60  A=60 C=120

Step-by-step explanation:

B=60 linear pair

A=60 corr. angle w.r.t. B

C=120 corr. angle w.r.t. 120

Answer 2

Answer:

a is 60, b is 60, c is 120

Step-by-step explanation:

since the opposite sides are parallel to each other, it is a parallelogram.

therefore adjacent angles sum up to 180°

hence angle b is 180-120 = 60°

if we close the parallelogram, the angle opposite to 120° will also be 120°, therefore angle is 60° and angle c will be 120°
