Question

WHAT'S Z? PLEASE HELP, URGENT!

Answer 1

`\large\boxed{z=(15\sqrt3)/(2)}`

Explanation:

We have the right triangle 30° - 60° - 90°. The sides are in ratio

1 : √3 : 2. Look at the picture.

`15=2x\to2x=15` divide both sides by 2

`(2x)/(2)=(15)/(2)\\\\x=(15)/(2)`

`z=x\sqrt3\to z=(15)/(2)\sqrt3=(15\sqrt3)/(2)`
