Determining the value of x by finding the sum of interior angles

The video tutorial explains how to find the value of X in a quadrilateral by using the formula for the sum of angles. It starts with setting up the problem, explaining the formula, and then setting up and solving the equation to find X, which is determined to be 50 degrees.

What is the sum of all interior angles in a quadrilateral?

• 360 degrees

• 540 degrees

• 180 degrees

• 720 degrees

Which formula is used to calculate the sum of interior angles in a polygon?

• (n - 2) * 90

• (n - 2) * 180

• n * 180

• n * 90

How do you combine like terms in the equation 2X + 16 + 2X + 16 + X + 14 + X + 14?

• 6X + 60

• 8X + 60

• 10X + 60

• 4X + 60

What is the first step in solving the equation 6X + 60 = 360?

• Add 60 to both sides

• Divide both sides by 6

• Subtract 60 from both sides

• Multiply both sides by 6

What is the value of X when you solve the equation 6X = 300?

• 25

• 30

• 50

• 60
