Hope it helps

Answer 2

c = 18 cm

Explanation:

You want the length of the hypotenuse in the 30-60-90 triangle with a=9 cm and b = 9√3 cm.

Triangle theorem

The 30-60-90 triangle theorem tells you the ratios of side lengths are ...

a : b : c = 1 : √3 : 2

Using a = 9 cm, this tells us that ...

c = 2a = 2(9 cm)

c = 18 cm
