Answer:


\boxed {\tt D. \ x=52}

Explanation:

The 2 angles are 2x and 76. They are on a straight line together. Therefore they are supplementary and add to 180 degrees.


2x+76=180

Solve for x by isolating x on one side of the equation.

76 is added to 2x. The inverse of addition is subtraction. Subtract 76 from both sides of the equation.


2x+76-76=180-76\\2x=180-76\\2x=104

x is multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.


2x/2=104/2\\x=104/2\\x=52

x is equal to 52 and D is the correct answer.
