Quizplus · Accepted Answer

The triangle formed with sides 12 and 16 (assuming these are the lengths of two sides meeting at a right angle, given the context of finding sin θ) would be a right triangle. To find sin θ, where θ is the angle opposite the side of length 12, we use the definition of sine in a right triangle: sin θ = opposite/hypotenuse. The hypotenuse can be found using the Pythagorean theorem: √(12^2 + 16^2) = √(144 + 256) = √400 = 20. Therefore, sin θ = 12/20 = 3/5.
