Steb by step:
3x + x +20 + 32 =180°
4x +52 = 180°
-52 from both sides
4x = 128
divide both sides by 4
x = 32°
The answer is x=19.
Hope it helps! (:
Answer:
C
Step-by-step explanation:
Convert them all to the form y = mx + c
1)
4x + 3y = 15
3y = -4x + 15
y = -4/3 x + 5
2)
3x - 4y = -8
-4y = -3x - 8
4y = 3x + 8
y = 3/4x + 2
3)
y + 1 = 4/3(x - 6)
y + 1 = 4/3x - 8
y = 4/3x - 9
4)
y = 3/4x - 5
