I need HELP PLEASE I DINT UNDERSTAND THIS!!! ILL GIVE YOU BRAINLIEST

DONT ANSWER IF YOU DONT KNOW

Answer 1

1. It is a right angle because the lines are perpendicular.
21x+6=90
21x=84
X=4

2. The angles are equal to each other so:
23x-5=21x+5
2x=10
X=5

3. The angles add up to 180 degrees so:
180=(20x+5)+(24x-1)
180=44x+4
176=44x
X=4
