Step-by-step explanation:
36A) AB = 4/ sin 30° = 4/ 0.5 = 8 cm
36B) AC = 4/ tan 30° = 4/ 0.577 = 6.9 cm
36C) BD = 4/sin 45° = 4/ 0.707 = 5.7 cm
36D) area of ∆ABC = ½×6.9×4= 13.8 cm²
36E) sin A = sin 30° = 0.5

Answer:
62 square units
Step-by-step explanation:
Top or bottom is 5 x 3, surface area is 15
front or back is 3 x 2, area = 6
left or right is 5 x 2, area = 10
so total area is 2*(15 + 6 + 10) = 62 square units
