Find the missing side lengths. Leave your answers as radicals in simplest form

tino4ka555 [31]

We have the triangle 30° - 60° - 90°.

The lenght of the sides are in proportion: $1:2:\sqrt3\to a:2a:a\sqrt3$

$a=y\\2a=x\\a\sqrt3=5\\\\a\sqrt3=5\qquad\text{multiply both sides by}\ \sqrt3\\\\3a=5\sqrt3\qquad\text{divide both sides by 3}\\\\a=\dfrac{5\sqrt3}{3}\\\\2a=2\cdot\dfrac{5\sqrt3}{3}=\dfrac{10\sqrt3}{3}\\\\Answer:\ x=\dfrac{10\sqrt3}{3},\ y=\dfrac{5\sqrt3}{3}$

What is a percentage increase of 19.50 to 22.50

Inga [223]

To find the percentaje we need to divided the tataol by the amount we end up having.

22.50/19.50=1.15
then we multiply by 100
115%
Then to find the percentaje increase we subtract
115%-100= 15%
So it has an increament of 15%
