Answer 1

Since l ║ m, one of the two base angle of the triangle formed = 65°

Also, the other base angle is = 40° (Given)

Now,

Vertex angle = 180° - (65° + 40°)

= 180° - 105°

= 75°

Since a straight angle is formed by the transversal line,

x + 75° = 180°

x = 180° - 75°

x = 105°

Answer 2

Answer:

l is parrel to m

Step-by-step explanation:

one of the two base angles is 65

and the other is 40°

vertex angle=180°-(65°+40°)

=180°-105°

=75°

x+75°=180°

x=180°-75°

x=105°

hope it helps you..

thankyou..
