Question

Line I ll m, L1= 120° and L2=100°, find out L3 and L4.​

Answer 1

Step-by-step explanation:

angle 3 is 80° and angle 4 is 40°

Answer 2

Answer:

since l2=100° ,m=80°(sum of angles of transverse is 180)

3=m=80°(vertically opposite angles are equal)

since l1=120 angle near 3 =60° by linear pair.

by angles sum property of triangle

4+80+60=180°

4=40°

Step-by-step explanation:

3=80°

4=40°
