Question

# The values of x y, in the following figure is

- 30°,50°
- 40°,60°
- 50°,70°
- 45°,65°

Hint:

### In this question, we have to find the value of x and y using the figure given. We know that sum of angles formed in a straight line is always 180. So, using this formula we can find the required value of x and substitute in other equation formed to find the value of y.

## The correct answer is: 40°,60°

As CD is straight line

So, x + 20 + 3x = 180 [sum of angles in a straight line is 180]

4x = 160

x = 40

Also, AB is a straight line

So, 3x + y = 180 [sum of angles in a straight line is 180]

340 + y = 180

120 + y = 180

y = 60
