Answer 1

Answer:

hypotenuse. A. B. C a b c. In any right-angled triangle, ABC, the side opposite ... Find the length of the hypotenuse, AB. ... In triangle ABC in which C = 90◦, AB = 25 cm and AC = 17 cm.

Answer 2

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² = 7² + 4² = 49 + 16 = 65 ( take the square root of both sides )

AB = $\sqrt{65}$ → D
