Answer:
∠G = 37°
∠H = 143°
Step-by-step explanation:
As we know ,
Sum of supplementary angles is 180 degrees.
Hence sum of ∠G and ∠H is also 180 degrees
∠G + ∠H = 180
Substituting the given values in above equation, we get -
∠G = (x + 4)° = (33 + 4)° = 37°
∠H = (4x + 11)° = (33*4 + 11)° = 143°
-8(-4) + y = 37
32 + y = 37
y = 5
when x = -4, y = 5
Answer: 3
x = 72.5°
x = 1/2(80 + 65)
x = 145/2
x = 72.5
