​

Answer 1

Answer:

130 ° ok

mark me brainlist please guy

Answer 2

Answer:

Hola..

Step-by-step explanation:

Exterior Angle A = 100 ( Exterior Angle Property )

Angle A = 180 - Exterior Angle A ( Linear Pair )

Angle A = 180 - 100

Angle A = 80

Exterior Angle C = 120 ( Exterior Angle Property )

Angle C = 180 - Exterior Angle C ( Linear Pair )

Angle C = 180 - 120

Angle C = 60

Angle A + Angle C = 80 + 60

= 140
