Question

Please help shouldn't be 38?

Answer 1

Answer:

No it is D.52

Step-by-step explanation:

The angle has to equal 180 degrees.

180-76=104

52 time 2 equals 104

104=104

Answer 2

Answer:

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

Step-by-step 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.
