Let AO intersect BC at D

ΔAOB = ΔBOC = ΔAOC (SAS)

AB = BC = AC

ΔABC is equilateral

O is the circumcenter of equilateral ΔABC

Therefore, O is also the centroid of ΔABC

AO / AD = 2/3

2 $\sqrt{3}$ / AD = 2/3

AD = 3 $\sqrt{3}$

Right triangle ADB has ∠ABD = 60°

AB / AD = 2/ $\sqrt{3}$

AB / 3 $\sqrt{3}$ = 2/ $\sqrt{3}$

AB = 6

Perimeter of ΔABC = 6 + 6 + 6 =18

Answer:

The answer is " $\sqrt{12.5}$ "

Step-by-step explanation:

$\to (3,2), \ (6,1)$

Distance $=\sqrt{9+1}=\sqrt{10}$

midpoint height $=\sqrt{10+2.5}=\sqrt{12.5}$

let

Gradient $= \frac{1}{-3}$

Perpendicular Gradient $= 3$

midpoints $= (4.5, 1.5)$

Similar to perpendicular

Now I'll obtain the perpendicular bisector solution

An equation of the center circle $(4.5,1.5)$ radius will be $\sqrt{12.5}$ .

If the sales tax rate is 7.25% in California, then how much tax should a merchant charge in San Francisco for the sale of a $15

Semmy [17]

$15 x .0725 = 1.0875 which we have to round to $1.09
Notice how I changed the 7.25% to a decimal .0725 by moving it back two places.
