If cosX = -0.2, and x is in quadrant II, then what it the value of sinX

Tems11 [23]

$\sin x>0$ when $x$ is in quadrant II, so

$\cos^2x+\sin^2x=1\implies\sin x=\sqrt{1-\cos^2x}=\sqrt{1-(-0.2)^2}\approx1.02$

What is Y=2x-1 and Y=3x+2

Readme [11.4K]

Answer:

{y,x} = {-7,-3}

Step-by-step explanation:

- 3x = 2

y - 2x = -1

-3x + y = 2 -2x + y = -1

y = 2x - 1

(2x-1) - 3x = 2

- x = 3 x = - 3

y = 2x-1

x = -3

y = 2(-3)-1 = -7
