Supplementary angle 128 on the left side and 5x on the right side, what is teh vlaue of x, explain answer
Supplementary angles add up to 180 degrees.
Given that one angle is 128 degrees, the other angle would be:
180 - 128 = 52
Therefore, the other angle is 52 degrees.
On the right side, the angle is given as 5x. We know that this angle is 52 degrees.
So, we can set up the equation:
5x = 52
Solving for x:
x = 52 / 5
x = 10.4
Therefore, the value of x is 10.4.
