The length of the two legs of a right triangle are 18 cm and 24 cm what is the length of the hypotenuse of the triangle ?
a 30cm
b 36cm
c 42cm
d 48cm

A. 30cm

Step-by-step explanation:

You would need to use the Pythagorean Theorem to find the answer. The theorem is a^2+b^2=c^2.

A and B represent the legs and C represents the hypotenuse.

Now substitute the values: 18^2+24^2=c^2

Calculate the exponents: 324+576=c^2

Now add: 900=c^2

Find the square root of 900: 30

So, the length of the hypotenuse is 30cm.
