Question

if one of the pairs of interior angles formed by intersecting two parallel lines with an intersection is 70,what is the measure of the other angle.
1)20⁰
2)70⁰
3)110⁰
4)140⁰​

Answer 1

Answer:

3) 110°

Step-by-step explanation:

∵ The sum of interior angle is always supplementary

∴ 70° + ∠B = 180°

∠B = 180° - 70°

∠B = 110°

Answer 2

Answer:

the measure of the other angle is 110⁰
