If the hypotenuse of a right triangle is 122 inches long and another side of the triangle is 22 inches long. how long is the remaining side?

Answer 1

Being a right- angled triangle apply Pythagoras.

h^2 = a^2 + b^2

Hence

b^(2) = h^2 - a^2

b^(2) = ( h + a)(h - a)

b^2 = (122 + 22)( 122 - 22)

b^2 = 144(100)

b^2 = 14400

b = sqrt(14400) = 120 .

Answer 2

Use the Pythagorean theorem to answer this question. In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides. The equation usually looks like this: c2 = a2 + b2, where c is the hypotenuse; a and b are the other two sides. In this example, 1222 = 222 + b2. Solving for b, b2 = 14884 - 484, b2 = 14,400, b = square root of 14,400 or 120.
