Question

Please help me! I need this answer

Answer 1

Answer:

For the first 3 questions, fill out exactly what you see in the picture. So, the first answer is $9\sqrt{2}$, the second one is x, and the third one is y. Now, since we know this is a 45 - 45 - 90 triangle, we can figure out all of the other sides. AB is the same as AC, so your answer for the fourth one question will be $9\sqrt{2}$. The hypotenuse in a 45 - 45 - 90 triangle is a side times $\sqrt{2}$, so your last answer will be $(9\sqrt{2})(\sqrt{2}) = 18$.
