Question

find the value of the x in the fig:-
​

Answer 1

Answer:

As, Sum of linear angles is 180

Now, 3x-5+55+x+20 = 180

or, 4x = 110

or, x = 27.5

Answer 2

Step-by-step explanation:

in following figure,

3x - 5 + 55 + x + 20 = 180 _ _ _ _sum of angles are make stright line is 180

3x + x +55 + 20 - 5 = 180

4x + 75 - 5 = 180

4x + 70 = 180

4x = 180 - 70

4x = 110

x = 110 / 4

x =27.5
