Question

In the figure. line p ║ line q. line l ║ line m. Find measures of ∠a, ∠b, and ∠c, using the measures of given angles. Justify your answers.

Answer 1

as p || q and l is transversal so angles on same side of transversal will be supplementary so a = 100°
now angle adjacent to b is corresponding to angle a so a = 80°
and b is corresponding to c so c = 80°
hope its brainliest material.

Answer 2

Answer:

a=100°

b=80°

c=80°

Step-by-step explanation:

p line is parallel to q line and l line is a transverse line intersecting p and q line.

Hence, a+ 80° =180°, ⇒a=100° (Answer)

Again l line and m line are parallel and q line intersects them transversely.

Hence, a+b =180°, ⇒ 100°+b =180°, ⇒ b= 80°. (Answer)

Now, p line and q line are parallel to each other and m line intersects them transversely.

Hence, angle b= angle c = 80°.(Answer)
