Triangle Angles and Equations

The video tutorial explains how to find the missing interior angle of a triangle. It begins by stating that the sum of the interior angles of any triangle is 180 degrees. The tutorial sets up an equation with the given angles and solves for the missing angle, X, by subtracting the sum of the known angles from 180. The solution reveals that the missing angle is 101 degrees.

What is the sum of the interior angles of any triangle?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

If one angle of a triangle is 32 degrees and another is 47 degrees, what is the equation to find the missing angle X?

• X + 32 + 47 = 90

• X + 32 + 47 = 180

• X + 32 + 47 = 270

• X + 32 + 47 = 360

What is the simplified form of the equation X + 32 + 47 = 180?

• X + 79 = 180

• X + 79 = 90

• X + 79 = 270

• X + 79 = 360
