Answer:
Net for the prism will have 3 rectangles with dimensions 5 by 15, 12 by 15 , and 13 by 15, and 2 triangles with legs 5 inches and 12 inches.
The correct net is net a.
Surface area = sum of areas of the three rectangles and sum of the two triangles.
SA = (5 x 15) + (12 x 15) + (13 x 15) + (5 x 12) = 75 + 180 + 195 + 60 = 510 square inches.

Answer:
AB ≈ 7.08
Step-by-step explanation:
Cos θ = adjacent / hypotenuse
where θ = 20° , adjacent = 7 and hypotenuse = AB
cos 20 = 7 / AB
cos 20 × AB = 7
AB = 7/Cos 20
AB = 7 / 0.989
AB = 7.077
AB ≈ 7.08
