1. find the value of x and y

2. find the value of x and y

explain

Step-by-step explanation:

Look at the pictures.

1.

We have the triangle 30° - 60° - 90°. The sides are in proportion 1 : √3 : 2.

Therefore:

2.

We have the triangle 30° - 60° - 90°. The sides are in proportion 1 : √3 : 2 and the triangle 45° - 45° - 90°. The sides are in proportion 1 : 1 : √2.

Therefore:

The common side of the green and pink triangle also has a length of x = 15.

Let the other side of the green triangle be marked with z.

Then:

         multiply both sides by √3

       divide both sides by 3

i don't even know man. edge inuity be messing with us. i had to ask a question too.
