Answer:
∠ ABC = 87°
Step-by-step explanation:
∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so
2x - 17 + x + 32 = 180 , that is
3x + 15 = 180 ( subtract 15 from both sides )
3x = 165 ( divide both sides by 3 )
x = 55
Then
∠ DBE = x + 32 = 55 + 32 = 87° , thus
∠ ABC = ∠ DBE ( vertical angles )
∠ ABC = 87°
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
Find y:
8x-y=40
y = 8x - 40
slope = 8

Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
A(1, 4 ) → A'(1, - 4 )
B(3, - 2 ) → B'(3, 2 )
C(4, 2 ) → C'(4, - 2 )
