Answer:
B- y=-3
Step-by-step explanation:
The slope is 4/5
You would get the equation in y = mx + b form
m (slope) will be the coefficient of x
-12 x -12 = 144 I’m pretty sure if not then it is something different
The answer is C) 160.
We know this because if mA = 50, we know that mC must also be 50. This is due to the fact that AB = BC. This leaves us with mB as 80 since the angles of a triangle always have to equal 180.
Now knowing this, it is easy to find the arc lengths in degrees. When you have a transcribed triangle, all we are going to do here is double the angle of the triangle to get the arc measure.
mB = 80
80*2 = 160
