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
1st one is 512L
2nd one is 125mL
let me know if im wrong
The answer is 45 because supplement means the sum of 180 so 180 divided by 4 is 45 and t=45
