Question

In figure 1₁ || 12, then the value of x is​

Answer 1

Answer:

The value of x is 100°.

Given-

l₁ is parallel l₂

One angle of triangle = 45°

Other angle of triangle = 35°

Let the third angle be 'Y'

Let the angle formed on the line l₂ be 'A'

To find-

The value of x.

Step-by-step explanation:

As we know the sum of all angles of a triangle is 180°

45° + 35° + Y = 180 °

80° + Y = 180°

Y = 180° - 80°

Y = 100°

Y = A ( as they are vertically opposite angles)

A = 100°

∴ A = x ( as it they are co-interior angles)

∴ The value of x = 100°
