Answer:
2pi/3 has the same Sin, Cos, & Tan as pi/3 in QI except for the SIGNS.
2pi/3 is in QII so Cos is negative and Tangent is negative, Sine is still positive.
Sin 2pi/3 = √(3) / 2
Cos 2pi/3 = -1/2
Tan 2pi/3 = -√3
Step-by-step explanation:
$27.79. First multiply the percentage as a decimal out of 100. Subtract that number from the original amount. Do the same thing with the number you got from subtracting(multiply by percentage then subtract from starting amount(the new one)) you end up with $27.79
-1 > (x + 4) / 2....multiply both sides by 2, eliminating the 2 on the right
2 * -1 > x + 4
-2 > x + 4 ....subtract 4 from both sides
-2 - 4 > x
-6 > x or x < -6
graphed : open circle (because there is no equal sign)...on -6, shading to the left
I think it’s 90 degrees
But idk
