In the unit circle

\cos ^2x+\sin ^2x=1x^2+y^2=r^2

Where r is the radius of the circle

x- coordinate represents cos angle

cos angle = x/r

Since r = 2

cos angle = x/2

y-coordinate represents sin angle

sin angle = y/r

sin angle = y/2

Because the question is incomplete

we can not find which is true

Level 3<br> Solve: |x + 2|– 5 = -1
leonid [27]

Answer:

x=−6

x=2

Step-by-step explanation:

Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side. Remember to follow the order of operations.

∣x+2∣−5=−1

Add 5 to both sides of the equation.

∣x+2∣=4

Use the definition of absolute value.

x+2=4

x+2=−4

Subtract 2 from both sides of the equation.

x=2

x=−6
