Answer:
5√10
Step-by-step explanation:
5 √10. You’re first getting the hypothenuse of 12^2+5^2= √169 which is 13. Then the hypothenuse of point A to B, which is 9^2+13^2= √250, which is 15.8113883008419, otherwise known as D. 5√10.
√250 = √(5^2x10) = 5√10
I’m not a tutor or anything. Just basic math I learned back in school.
