Question

Please help me! I need this answer

Answer 1

For the first 3 questions, fill out exactly what you see in the picture. So, the first answer is
`9√(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√(2)`. The hypotenuse in a 45 - 45 - 90 triangle is a side times
`√(2)`, so your last answer will be
`(9√(2))(√(2)) = 18`.
