Example: How Tall is The Tree? We can't reach the top of the tree, so we walk away and measure an angle (using a protractor) and distance (using a laser): We know the Hypotenuse; And we want to know the Opposite; Sine is the ratio of Opposite / Hypotenuse: sin(45°) = Opposite Hypotenuse. Get a calculator, type in "45", then the "sin" key:
