Remember How to identify the sides of a triangle: Hypotenuse is always the longest side and opposite the 90° angle. θ hypotenuse

Remember How to identify the sides of a triangle: The adjacent side is the one right beside the angle θ (that is not the hypotenuse) θ hypotenuse adjacent

Remember How to identify the sides of a triangle: The opposite side is opposite the angle θ. It is the one side that does not touch the angle θ θ hypotenuse adjacent opposite

Remember θ Soak a toe

Find a side length If we know an angle and a side, we can calculate a side length. Which side is x? opposite, adjacent or hypotenuse? 36.87° 5 x 3
