Answer:
Segments AB and CD are perpendicular to each other.
Step-by-step explanation:
If you were to convert line segments AB and CD into slope-intercept form(y=mx+b), you would get y=-5x+1 for AB and y=1/5x-5.
Any line with a slope that is flipped-oppisite (-5/1 to -1/5 to1/5)
of another line must be perpendicular to each other. It doesn't have to have the same y-intercept, it just makes the intersecting point different.
15% and the corresponding 0.15 is by necessity unit-less; it's just a multiplier. If you run up a $1 bill and wish to tip 15%, multiply $1 by 0.15, obtaining $0.15.
Then the total due would be $1 plus $0.15, or $1.15.
Note that $0.15
-------- = 0.15 is unit-less

2x + x + 33 = 90
3x + 33 = 90
3x = 57
x = 19
Angle 1 = 38°
