Well x is an obtuse angle
but the angle e,f,g is an acute angle
A^2 + 9 = 36 now solve subtract 9 from both sides to get a^2 = 27 then find the square root of 27 and that should be your answer so like 5.196 something
the functions are both increasing
the functions for plan II had a greater unit rate
and the functions for plan I has a greater y intercept
