Question

i hope U can Solve it​

Answer 1

Answer:

c = 30 , b = 40  and a = 20

Step-by-step explanation:

if they are all paralell so 4c = 3b = 6a

we know that p and q , l and m and n are paralall so

4c = 120°

c = 120/4

c = 30°

so

3b = 120°

b = 120/3

b = 40°

so

6a = 120°

a = 120/6

a = 20°

Answer 2

Answer:

a = 20 , b = 40 , c = 30

Step-by-step explanation:

As lines p and q are parallel,

4c = 120 degrees (corresponding angles)

c = 120/4

c = 30

As lines m  and n are parallel,

3b = 120 (corresponding angles)

b = 120/3

b = 40

If we join the lines m, l , p, q we get a rectangle (refer the attachment)

6a= 120 (Opposite angles are equal in a rectangle)

a = 120/6

a = 20
