Answer:
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.
