We know that AB is perpendicular to CD. (that was given)
Perpendicular angles are 90 degrees because two straight lines (180) crossed make 4 90 degree angles.
180+180=360
90*4=360 See the similarities?
7x+6= 90 degrees
Subtract 6 on both sides.
7x=84
Divide both sides by 7.
x=12
"B" is the correct answer.
I hope this helps!

What is the question?
Step-by-step explanation:
Answer:
10 miles
Step-by-step explanation:
Let m represent the number of miles Kayla runs. We want to find m such that ...
0.50m = 5.00
Divide by the coefficient of m:
m = 5.00/0.50 = 10
Kayla has to run 10 miles to get the same donation from both parents.
Yes the fractions are equivalent. 5/5 is another equivalent fraction
