Answer 1

Answer:

100° is the correct answer

Answer 2

Given : ‘l’ and ‘m’ are intersected by a transversal ‘n’

To Find :Is l || m?

Solution:

$\angle PQA = 100^{\circ}$

$\angle PQA+\angle AQR = 180^{\circ}$(Linear pair)

$100^{\circ}+\angle AQR = 180^{\circ}100$

$\angle AQR = 80^{\circ}$

We are given ∠CRS = 80°

So, ∠CRS = 80° = ∠AQR

∠CRS and ∠AQR are corresponding angles

Since ∠CRS = ∠AQR corresponding angles are equal
