Question

in the given figure l || m.find the value of x ​

Answer 1

Answer:

GIVEN - L is perpendicular to m

TO FIND - value of X

Const. - please refer to the above attachment.

- construct a line which bisects the angle

( 3x+ 10) °

SOLUTION -

Angle 1 = 40° ( lines are parallel so interior alternate angles form are equal)

Angle 2 = 60° ( alternate angles are equal)

Angle 1 + Angle 2 = 3x + 10

40 + 60 = 3x + 10

100 = 3x+ 10

100- 10 = 3x

90= 3x

90/3 = X

30= X

X= 30°
