Question

work out the value of x

Answer 1

Answer:

20°

Step-by-step explanation:

As interior angles made by cutting a line by two parallel lines sum up 180°.

So,

4x + 5x = 180°

9x = 180°

x = 20°

Method 2 :-

Angle adjacent to angle 4x on same side is equal to 180° - 4x and is equal to 5x because of corresponding angles.

So,

180° - 4x = 5x

180° = 9x

20° = x

Answer

So, value of x is 20°.

Thank you.

Have a Nice Day!
