Answer:
18
Step-by-step explanation:
The longest side of the triangle is known as the hypotenuse. To find the hypotenuse, you would use the equation a^2+b^2=c^2.
The a and b represent one side of the triangle so it wouldn’t matter which side you use for them. The c represents the hypotenuse.
When you plug in the side lengths, the equation would be:
10^2+15^2=c^2
100+225=c^2
325=c^2
Now you find the square root of 325 which is approximately 18,
And so the final answer is 18.
