-8.70833333333 about but you can round to the nearest tenth (-8.7) or nearest whole number (-9)
Bro I got a video of those test answers just message me ur phone # I got all the geometry tests
Just make a triangle and an X and Y axis and reflect it over the Y axis. It's that simple. Then tell how you did it. Obviously it will be a reflection. Name the points (before and after) and you are done.
-Twix
Angle A and angle B sums up to 180 (interior angles)
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
angle A = 6(18)-35 = 73 degrees
It represents simulations
