Question

Two lines are parallel and one of the line is transversal.If angle 1 and angle 5 are corresponding angles and angle 1 and angle 2 are adjacent angles , angle 2=100°then find out angle 5. *
1 point
90 degree
80 degree
100 degree

Answer 1

Answer:

the answer is 80

Step-by-step explanation:

adjacent angles in parallel lines is supplementary

angle 1 +angle 2= 180

angle 1 = 180-100

angle 1 = 80°

corresponding angles are congruent

angle 1 = angle 5

therefore,angle 5= 80°
