Question

Special right triangles Find the value of each missing variable

Answer 1

Hi!

Rules for solving 30-60-90 triangles are as follows:

* The hypotenuse is double the short leg.

* The short leg times √3 is the long leg

To solve then, we divide 4√21 by √3 and get 4√7. That is x, and to get y we multiply by 2. That is 8√7.

Hope this helps! :D
