Question

Use the ratio of a 45-45-99 triangle to solve for the variables. ​

Answer 1

Answers:

`a = 18√(2)`

`b = 18`

==============================================================

Step-by-step explanation:

For any 45-45-90 triangle, the two legs are the same length. We consider triangles like this to be isosceles. So we have b = 18 as the vertical leg because the horizontal leg is also 18 units long.

The hypotenuse of these types of triangles is always
`√(2)` times longer compared to the leg length. So the hypotenuse is
`a = 18√(2)`

As an alternative, you can use the pythagorean theorem to find the hypotenuse.
