Triangle jkl is isosceles. the meansure of angle j is 72degrees and the measure angle k is 36 degrees. which satement describes angle l?

I'm not exactly sure what kind of answer you are looking for but angle L would also be 72 degrees. This is because 36 (K) + 72 (J) = 108 and a triangle's angles must add up to 180 so 180 - 108 = 72 (L) . This also makes sense because it is an isosceles triangle so two of the angles must be the same because two of the sides are the same length. 

The surface area would be 576 because you multiply all the numbers then multiply that number by 6
