Geometry Solve for Missing Angles

What is the third angle of a triangle whose 1st angle is 34 and 2nd angle is 101?

• 32

• 39

• 45

• 54

What do the angles in an equilateral triangle measure?

• 30, 60, 90

• 45, 45, 90

• 60, 60, 60

• 35, 55, 90

An angle whose measure is exactly 90 degrees.

• acute

• vertical

• right

• straight

What is the value of the missing angle?

• 61

• 50

• 60

• 69

• 146
• 34
• 36
• 136

Angle A says it's 10x + 24

Angle B is 6x + 72

How would you set up to solve for x?

• 10x + 24 = 6x + 72

• 10x + 24 + 6x + 72 = 180

• 10x + 24 - ( 6x + 72) = 180

• 10x + 24 = -6x - 72
