Question 3 
In the given fig. I is parallel to m and p ll q. Find the measure of each of the angles a,b,c,d.

​

Answer 1

Step-by-step explanation:

<d=100°, as vert. opp. angles.

<d=<b, as corr. angles. So, <b=100°.

<a=180-100, as <a, and, <b, r co interior angles.So, <a=80°.

<c=180°-80°, as, <a, and, <c, r co intrerior angles.

So, <c=100°.

<a=80°, <d=100°, <b=100°, <c=100°!!!
