supplementary angles = 180 degrees
so x = angle 1
y = angle 2
y = 3x-12
x + 3x-12 =180
4x-12 = 180
4x = 192
x = 192/4 = 48
y = 3(48) -12 = 144-12 = 132
132 +48 = 180
the angle is 132
This is the answer I got according to the app called “Math”
Answer:
Question 6a, 3. 6b, -6, 6c, -3
Question 7, 3x^3-x^2-x-4-5/x-1
Question 8, x^2-x+1
Question 9a, x^2+14x=40
9b, x^2-2x-80
9c, 9x^2-3x-20
9d, 9-4x^2
