Multiply the first equation by 2 or divide the second one my 2, to get the #X opposites, to cancel each other out

-4x+6y=12
4x-6y=-6

Or

-2x+3y=6
2x-3y=-3

there’s no solution either way

The answer is 200.96 cm^2.

2*3.14*r=50.24

=>r=50.24/6.28

=>r=8 cm

I need help with number 13, PLEASE. Extra points!
gladu [14]

Answer:

90°, 270°

Step-by-step explanation:

2r sin(Ф/2) = c

2r sin (Ф/2) = √2r

divide both sides by 2r

sin (Ф/2) = √2r/2r

sin(Ф/2) = √2/2

From the unit circle sin is √2/2 at 45°, and 135°

so Ф/2 = 45

Ф=90°

and Ф/2 = 135

Ф= 270°
