A rotation on its axis of 180 degrees
Im pretty sure its b im soo sorry if im wrong.
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!

8p +5 = $29
The above is the equation
If you want to know how many pizza were ordered then you subtract 5 from each side of the equal sign then you would have 8p=24 then divide by 8 on both sides of equal sign . p= 3 ; so 3 pizzas were order plus a charge of $5 for delivery.
Rearrange the equation to get:
y = 3x - 7
From this you can see that:
m = 3, b = -7
