Answer:
The value of x
= 3x - 5 +4x = 180 ( a/q corresponding angle concept)
= 3x +4x = 180 + 5
= 7x = 185
= x = 185 / 7
= x = 26.4

Answer:
As the line l,m are parallel.
We know that,
Sum of corresponding angles is 180°
(3x-5)+4x=180
7x-5=180
7x=185
x=185/7
x=26.4
So,the angles are (3x-5)=74.2
4x=105.6
