-42 x -16 = 672
Simplest form, or product, is 672.
Answer:
<ABC = 54 degrees
Step-by-step explanation:
Taking the sum of angle on the straight line ABD as 180 degrees
3x+9 + 9x - 9 =180
12x = 180
x = 180/12
x = 15 degrees
Since <ABC = 3x+9 (vertically opposite angles)
<ABC = 3(15)+9
<ABC = 45+9
<ABC = 54 degrees
Kinda low, you would need luck to be on your side!
Y - 9 = 2(x - 1)
This is because the base equation is below:
y - y1 = m(x - x1)
