Question

Find the length of the hypotenuse of a right triangle with legs measuring 7 cm and 9 cm. Round your answer to the nearest tenth.

Answer 1

Hypotenuse = 11.4 cm

Explanation:

Hypotenuse ² = opposite ² + adjacent ²

Opposite = 7 cm

Adjacent = 9 cm

Hypotenuse ² = opposite ² + adjacent ²

= 7² + 9²

= 49 + 81

Hypotenuse ² = 130

Hypotenuse = √130

= 11.40

Hypotenuse = 11.4 cm
