At a point, 16 yards from the base of a tower, the distance to the top of the tower is 4 yards more than the height of the tower. The Pythagorean Theorem states: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle). We can label the 10 feet as side a and the 30 feet as side b. Take a square root of sum of squares: c = √(a² + b²) Given angle and one leg; c = a / sin(α) = b / sin(β), from the law of sines; Given area and one leg; As area of a right triangle is equal to a * b / 2, then In a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse. The hypotenuse of a right triangle is calculated by finding the square root of the sum of the squares of the triangle's legs. Every triangle has three heights, or altitudes, because every triangle has three sides.
