Forgive me if this is wrong. I haven't done stat in a year, but comment if you need clarification!
She read 11 books because 44 divided by 4 its 11$
144=(x+7)^2 take the square root of both sides...
12=x+7 subtract 7 from both sides...
x=5
So the original was a 5m square.

255=WL and you are told that W=L+2 so the equation becomes:
255=(L+2)L
255=L^2+2L
L^2+2L-255=0
L^2+17L-15L-255=0
L(L+17)-15(L+17)=0
(L-15)(L+17)=0 Since L>0...
L=15yd, and since W=L+2, W=17yd so
length=15, width=17yd
This picture is depicting a straight line, therefore all we have to do is subtract 76 from 180. You get 104
Your answer is 104 degree
