The interior angles formed by the sides of a quadrilateral have measures that sum to 360°. What is the value of x?

Enter your answer in the box.

x = ?

A polygon with hash marks on the two sides, the left side labeled four X plus twelve and the right side labeled sixty but here's the picture.

x = 59

Step-by-step explanation:

Equations

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

The image shows a four-sided polygon and its four angles measures, thus we sum them all and equate the sum to 360:

x + x + 2x + 3 + 2x + 3 = 360

Simplifying:

6x + 6 = 360

Subtracting 6:

6x = 354

Dividing by 6:

x = 354/6

x = 59

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
