The first answer in Question A is Business Plan and the second answer is $3 less.
The first answer in Question B is 12 and the second answer is Residential Plan.
The answer is V=0.3157=0.32
Since they are equal to 90 degrees. (complimentary angles)
6x-11+7x+10= 90
Combine like terms.
13x-1= 90
Add one to both sides.
13x= 91
x= 7
Plug that into the b.
7(7)+10
49+10
59
I hope this helps!
