Question

HELP! Two lines intersect at a point, forming ​ ∠1 , ∠2 , ∠3 , and​ ​ ∠4 ​ .

∠1 and ∠3 are vertical angles.

∠2 and​ ​ ∠4 are vertical angles.

m∠1=70°

What is the measure of ​​ ∠2 ​?

Answer 1

Answer: 110 degrees

------------------------------------------------------------------

Angle 2 is supplementary with angle 1, as they form a straight angle
This means the two angles add to 180 degrees

(angle 1) + (angle 2) = 180
(70) + (angle 2) = 180
angle 2 = 180 - 70
angle 2 = 110 degrees
