Find the measure of the missing angles.
100°
b =
C=

<b = 80

<c = 80

Step-by-step explanation:

<b and 100 form a straight line so they add to 180

<b +100 =180

<b = 180-100

<b = 80

angles b and c are vertical angles and vertical angles are equal

<c = <b = 80

b+100 = 180° (straight line angles)

b= 180°- 100°

b= 80°

c= b (vertically opposite angles)

c= 80°

mean, 40.6
