Answer: 18
Explanation:
So this is referencing the Pythagorean theorem. It states that the two shorter sides squared, in your case 10 and 15, is equal to the longest side, or hypotenuse squared.
Step by step
1. Calculate both the shorter sides squared: 10*10= 100 and 15*15= 225
2. Add the 2 shorter sides: 100 + 225 = 325
3. Find the square root of 335: √(325) = 18.0277563773
4. Round to the nearest integer: 18
