consider the diagram of supplementary angles

Question

One side is 128 dgerees
The other is 5x
whats the value of x

Answer 1

Since the angles are supplementary, their sum is 180 degrees.

So, we have:

128 + 5x = 180

Subtracting 128 from both sides, we get:

5x = 52

Dividing by 5, we get:

x = 10.4

Therefore, the value of x is 10.4.
