Question

Here line L is parallel to m and line p is parallel to q find a,b,c​

Answer 1

60°+a=180° (sum of consecutive interior angles is 180°)

=>a=180°-60°

=>a=120°

<a=<e(corresponding angles)

=> <e=120°

<e=<d (vertically opposite angles)

=> <d=120°

<d+<b=180° (linear pair)

=> 120°+<b=180°

=> <b=180°-120°

=> <b=60°

<b=<c (vertically opposite angles)

=> <c=60°

so,<a=120°,<b=60° and <c=60°.
