Question

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

Answer 1

Answer:

<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

Answer 2

b+100 = 180° (straight line angles)

b= 180°- 100°

b= 80°

c= b (vertically opposite angles)

c= 80°
