Question

WHAT'S Z? PLEASE HELP, URGENT!

Answer 1

Answer:

$\large\boxed{z=\dfrac{15\sqrt3}{2}}$

Step-by-step 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

$\dfrac{2x}{2}=\dfrac{15}{2}\\\\x=\dfrac{15}{2}$

$z=x\sqrt3\to z=\dfrac{15}{2}\sqrt3=\dfrac{15\sqrt3}{2}$
