Question

if l1 // l2 then the value of x is
​

Answer 1

Answer:

Step-by-step explanation:

The third angle will be 100° from the anglesum property of the triangle.

So,

x = 80° as l1 is parallel to l2.

Answer 2

In the triangle formed by the two lines ........

y° + 45 + 35 = 180 (angle sum property)

y = 100

x + y =180 (co - interior angles are supplementary)

x + 100 = 180

x = 80°
