Answer:
x + (x + 40) = 180°
2x + 40 = 180°
2x = 180-40
2x = 140
x = 140/2
Ans . x = 70

Given:
x° and [x+40]° are supplementary to each other.
To find:
The value of x.
Solution:
The value of x is 70°.
To answer this question, we will follow the following steps:
As we know that if two angles 'a' and 'b' are supplementary to each other, then their sum is equal to 180°.
Now,
as given in the question,
We have two angles- x° and [x+40]° that are supplementary to each other.
So,
Hence, the measure of x is 70°.
