Answer:
46 degrees.
Step-by-step explanation:
Sin(angle) = 5/7. Using a calculator, this angle is thus 45.6, or approximately 46 degrees.
Each trianglar side has an area: (1/2)*8*9=36
the base is a square with an area of 8*8=64
so the total surface area is 36+36+36+36+64=208

We don't know what ( 5 2 , 7 2 ) is supposed to represent, but it seems unlikely that the sum of those numbers is -6. Hence that is not a solution to the system.
The sum of -4 and 10 is +6, not -6, so that point is not a solution, either.
Neither offering is a solution to the equations.
