#1Find the missing angle.

Triangle = 180o total.To find x, subtract what you know from 180.

#2Find the missing angle.

Circle = 360o total.To find x, subtract what you know from 360.

#3Find the missing angle in the right angle.

Right Angle = 90o total.To find x, subtract what you know from 90.

#4What is the measure of one of the angles in the

yield sign?

The yield sign is an equilateral triangle.All 3 angles are equal.The total of the angles = 360o.

#5Find the missing angle.

Quadrilateral = 360o total.To find x, subtract what you know from 360.

#6Find the missing angle.

Linear Pair: A + 50 = 180o
