Question
The value of x from the following figure is

- 40°
- 50°
- 60°
- 45°
Hint:
In this question, we have to find the value of x using the given figure. As we know that sum of all the angles formed in the straight line is 180
. So, by using this we can find the value of y and then substituting it in the other equation formed to find the value of x.
The correct answer is: 40°

As AC is a straight line
So, 2y+30
+ y= 180
[sum of angles formed in a straight line 180
]
3y = 150
y = 50
Also, EB is a straight line
So, 90
+ x + y =180
[sum of angles formed in a straight line 180
]
90
+ x + 40
= 180
x = 40
