Sagot :
Answer:
∠ a = 60° , ∠ b = 120°
Step-by-step explanation:
Supplementary angles sum to 180° then
x - 40 + x + 20 = 180 , that is
2x - 20 = 180 ( add 20 to both sides )
2x = 200 ( divide both sides by 2 )
x = 100
Then
∠ a = x - 40 = 100 - 40 = 60°
∠ b = x + 20 = 100 + 20 = 120°
Answer:
x=100 a=60 b=120
Step-by-step explanation:
Supplementary angles add 180 degrees
(x-40) + (x+20) = 180
2x-20 =180
2x =100
x = 100
100-40 = 60
100+20 = 120
60+120 +180
