Question

In XYZ right angled at Y. find the length of the hypotenuse if the length of the other two sides is 1.6 cm and 6.3 cm.

Answer 1

9514 1404 393

Answer:

6.5 cm

Explanation:

The Pythagorean theorem applies. You want c for a=1.6, b=6.3.

c² = a² +b²

c² = 1.6² +6.3² = 2.56 +36.69 = 42.25

c = √42.25 = 6.5

The length of the hypotenuse is 6.5 cm.
