GeometryLesson 4.1 & 4.2

Find the measure of the missing angle.

• 90^o
• 10⁰
• 130^o
• 50^o

In a triangle, how many total degrees are there?

• 100%

• 180 degrees

• it varies

• 360 degrees

What does the equation look like to solve for x?

• 8x + 2 + 70 = 180

• 8x +2 + 60 = 180

• 8x + 2 + 60 + 70 = 180

• 8x + 2 = 180

Solve for x.

• x + 53 = 65

• 70 + 65 + x + 53 = 180

• x + 53 = 70

• x + 53 = 180
