Question

In the figure given below, l║m, ∠A =1000

and ∠B = 300

, find the

measure of ∠x.​

Answer 1

Answer:

∠x = 130°

Step-by-step explanation:

Given

∠A =100°

∠B = 30°

∠A = ∠D (Corresponding angles are equal)

100° = ∠D

∠x = ∠B+∠D (The exterior angle sum of the two opposite interior angles)

= 30° + 100°

= 130°

Hope it helps!!

Answer 2

Answer:

angle x = 130⁰

Step-by-step explanation:

Given,

angle A= 100⁰,

angle B= 30⁰,

& l || m.

angle CDB = angle A = 100⁰

( corresponding angles of parallel lines are equal)

This x would be equal to, angle CDB + angle CBD

( angle x is the exterior angle of the triangle CDB )

100 + 30 = 130⁰ = angle x.
