Question

solve the above question​

Answer 1

Answer:

Vertically opposite angles are equal.

So, c = a & r = p & q = s

Alternate external angles are equal.

So, c = r

Sum of linear angles is 180°.

So, p+q = 180°

Substitute the values. You will get

a = 50°, q = 130°, r = 50°, s = 130°

Answer 2

Answer:

a=130

r=130

l=q=s=50

Step-by-step explanation:

angle l =q

alternate interior angles are equal

angle q=s

vertically opposite angles are equal

angle l+a=180

angle l=50

angle a=180-50=130

angle a =130

linear pair

angle s+r=180

angle s=50

angle r =180-50=130
