Question

The hypotenuse of a right triangle is 25 cm, and the shorter leg is 15 cm. Find the length of the other leg. 2 cm cm 20 cm

Answer 1

a² + b² = c²

15² + b² = 25²

b² = 25² - 15²

b² = 400

b = √400

b = 20

.

Answer: The missing leg is 20 cm

Answer 2

Use the Pythagorean theorem

a^2 + b^2 = c^2

a^2 + 15^2 = 25^2

a^2 + 225 = 625

a^2 = 400

a = 20

Answer: 20 cm
