Find the missing side lengths
lora16 [44]

Answer:

the side lengths will be 4√2- 4√2 - 8

Step-by-step explanation:

When you have missing side lengths of a right triangle, you can use special triangles to find the side lengths.  Where the angles are 45-45-90, each triangle has side lengths with the relationship 1 - 1 -√2.

This means for problem 9, the side length 8 is the equivalent of the special triangle √2 * √32 = √64 = 8. So each side is multiplied by √32.

So the side lengths will be 4√2- 4√2 - 8.

These are found using:

1*√32 = √32 = 4√2

1*√32 = √32=4√2

√2*√32 = √64 = 8
