Understanding Angles and Solving for X

The video tutorial explains how to determine the value of x in a geometric problem by using the sum of angles in a complete rotation, which is 360 degrees. It sets up an equation with the given angles, simplifies it, and solves for x, resulting in x equaling 97.

What is the total sum of angles in a complete rotation?

• 180 degrees

• 270 degrees

• 360 degrees

• 450 degrees

Which equation represents the sum of the angles in the problem?

• X + X + X + 69 = 180

• X + X + X + 69 = 270

• X + X + X + 69 = 360

• X + X + X + 69 = 450

What is the simplified form of X + X + X?

• 3X

• 4X

• 5X

• 2X

After subtracting 69 from both sides of the equation, what is the resulting equation?

• 3X = 270

• 3X = 180

• 3X = 291

• 3X = 360

What is the value of X after solving the equation?

• 107

• 97

• 87

• 117
