Y=180-70 (interior)
y=110
the answer is D
Answer:
12/25
Step-by-step explanation:
48% is equal to 48/100
This can be simplified by dividing both the numerator and denominator by 4.
48/4=12
100/4=25
Use the equation of -b/2a, so if you have a line you can just plug in the numbers.
<span>A) 2x -5y +z = 1
B) 3 y + 2z = 5
C) -24 z = 48
Those 3 equations you typed were somewhat squished together.
Did I retype those correctly?
Let me know and I'll solve it.

B. 4 right angles
perpendicular lines always create 90° angles
