Question

Work out the value of x

Answer 1

x = 18°

Explanation:

2x + 2x + 3x + 3x = 180°

10x = 180°

x = 180° : 10 =

x = 18°

-----------------------

check

2 × 18 + 2 × 18 + 3 × 18 + 3 × 18 = 180°

the answer is good

Answer 2

x = 36

Explanation:

The two lines are parallel and intersected by a transversal line.

The co-interior angles formed will sum up to 180°

Here angles 3x and 2x are the co-interior angles

So 3x + 2x = 180

5x = 180

x = 180/5 = 36
