A right triangle has one side that measures 4 in. The angle opposite that side measures 80 degrees What is the length of the hypotenuse of the triangle? Round to the nearest tenth.

Use sine because the 4-inch side is opposite the 80° angle, and the hypotenuse is the longest side: sin(80°) = 4 ÷ hypotenuse. So the hypotenuse is 4 ÷ sin(80°) ≈ 4.1 inches, making “4 point 1 in.” the correct choice.
