That is a 30 60 90 triangle
The "short" side (DE) equals the middle side (FE) times (1 / sq rt(3))
short side = 8 * sqrt(3) * (1 / sq rt(3) = 8
Hypotenuse (DF) is 2 times the short side which equals 16.

The solution to the system of equations is (3,1)
Step-by-step explanation:
The system of equations represented by graph are:

Solving the system of equations
Let:

Putting value of y from eq(2) into eq(1):

So, Value of x = 3
Putting value of x into eq(2)

So, value of y= 1
So, The solution to the system of equations is (3,1)

That implies a simple multiplication, with a couple considerations:
17.5 percent = 17.5% = 17.5/100 = 175/1000
so we multiply both quantities:
17.5% of 2400
= (17.5%)(2400)
= (175/1000)<span>(2400)
</span>= 175*2400/1000
= 420
