Question

Find the value of unknown angles​

Answer 1

Step-by-step explanation:

40+x+x=180 (ANGEL SUM PROPERTY)

40+2x=180

2x=180-40

2x=140

x=70°

NOW IN ANGLE B

X(70°)+Y=180(LINEAR PAIR)

70+y=180°

y=110°

hope it helps

Answer 2

x=70

y=110

Step-by-step explanation:

By Angle Sum Property

x + x + 40° = 180°

2x+40 = 180

2x = 180 - 40

2x = 140

x = 140 /2

x = 70°

Linear Pair

y+70=180

y=180-70

y=110
