Jasmira has a new corner shelving unit that is triangular. The unit has three identical oblique triangle shelves. Jasmira wants to put some shelving paper down but isn’t sure how much to buy. If one side of each triangle is 22 inches, an adjoining side is 35 inches, and the angle formed between them is 87 degrees, then how much paper (to the nearest square inch) does she need to cover all 3 shelves?(1 point)

Area of one triangle = (1/2)ab sin(C) = (1/2)(22)(35) sin(87°) = 385·sin(87°) ≈ 385·0.99863 ≈ 384.47 in².
For 3 shelves: 3·384.47 ≈ 1153.42 in² → 1,153 in² (to the nearest square inch).
