Answer:
B (5 sqrt10)
Step-by-step explanation:
If the hypotenuse is 17, and a leg is 8, that makes the other leg equal to sqrt((17^2)-(8^2)) = sqrt(289-64) = sqrt(225) = 15.
Because you subtract 3 from the leg with length 8, that makes the smaller triangles leg 5. That makes the hypotenuse sqrt(5^2 + 15^2) = 5sqrt10
I'm guessing you typoed for B and meant 5sqrt10, so the answer is B
Answer:
Step-by-step explanation:
If you use Pythagorean's Theorem, the other side becomes 15.
We can now use the same Theorem to find x.
8 - 3 = 5
15^2 + 5^2 = 250
That simplifies down to
