Two angels are supplementary and their measures are 2x and 52. what is the value of x?

By definition, supplementary angles always add up to 180 degrees. So, if we know that one of the angles is 52, then we can set up our equation, which would look like: 2x+52=180. In terms of solving equations algebraically, we would first subtract 52 from the 180 in order to make the equation 2x = 128. Then we would divide each side of the equation by 2, cancelling out the 2 on the x and making it just x on one side and making the 128 into 64 on the other side. The final equation looks like this: x = 64.

So, the answer to this question is that x = 64.
