Question

 If x° and 2x° are co interior angles, find them.
(with process)​

Answer 1

Answer:

x = 60°

2x = 120°

Step-by-step explanation:

Sum of co-interior angles is always 180°

We are given that two co-interior angles are x and 2x and hence we can form the equations as

x + 2x = 180

3x = 180

x = 180/3

x = 60°

∴ measure of x = 60°

and measure of 2x = 2 × 60° = 120°

We can verify be adding the two to check if their sum adds upto 180° or not

x + 2x = 60 + 120 = 180°

Hence we can check our answer in the above manner as well.
