Aright triangle has a hypotenuse with a length of 130 cm. one leg has a length of 100 cm. what is the length of the other leg of the triangle?

Hey!

You have to use the Pythagorean Theorem.

a² + b² = c² is the same as: c² - a² = b²

c = 130

130² = 130 × 130 = 16,900

a = 100

100² = 100 × 100 = 10,000

16,900 - 10,000 = 6,900

√6,900 = 83.1

That means the length of the other leg is 83.1 inches

answer: c

(2, -4)

goes 7 to the

(9, 4)
