The surface area not including the top of the pool would be 748 ft(not sure if the teacher want you to add square to the end of it or not) .so 12*5 is 60 ,*2 =120. 24*5 =120. 120*2= 240. 24*12=288. so 288+240+120=748 ft(this would be the surface area of the pool.so if you need the volume of concrete needed to make the pool times the needed with of the concrete by the area ∆make sure if the needed thickness needed is in inches turn the area from feet to inches by multiplying it by 12 )
Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees
We can rule out choice I since acut means less than 90
II is a possibility, but it doesn't best describe it
III. that is true, but it doesn't include the isocileese part
IV. that is true, but doesn't include the acute part
not sure, either III or IV
Angle B is 45, angle A is 108, angle C is 27
