Use trigonometric identities to solve each equation within the given domain.
DedPeter [7]

Recall that

cos²(<em>x</em>) + sin²(<em>x</em>) = 1

Then in the equation

1 - cos(<em>x</em>) = 2 - 2 sin²(<em>x</em>)

we can rewrite as

1 - cos(<em>x</em>) = 2 (1 - sin²(<em>x</em>))

1 - cos(<em>x</em>) = 2 cos²(<em>x</em>)

2 cos²(<em>x</em>) + cos(<em>x</em>) - 1 = 0

Factorize the left side as

(2 cos(<em>x</em>) - 1) (cos(<em>x</em>) + 1) = 0

so that

2 cos(<em>x</em>) - 1 = 0   <u>or</u>   cos(<em>x</em>) + 1 = 0

cos(<em>x</em>) = 1/2   <u>or</u>   cos(<em>x</em>) = -1

On the interval (-<em>π</em>, <em>π</em>) (note that this interval is open, so we don't allow <em>x</em> = <em>π</em>), we have

• cos(<em>x</em>) = 1/2 for <em>x</em> = <em>π</em>/3 and <em>x</em> = -<em>π</em>/3

• cos(<em>x</em>) = -1 for <em>x</em> = <em>π</em>

PLEASE HELP I NEED IT TO PASS THIS CLASS

Answer:

Angle 5 = 37°

Angle 8 = 143°

Step-by-step explanation:

Angle 2 = Angle 8

Reason : Alternate exterior angles are equal.

Therefore,

Angle 8 = 143°

Angle 5 + Angle 8 = 180°

Reason : Angle 5 & 8 are in a linear pair.

Angle 5 + 143° = 180°

Angle 5 = ( 180 - 143 )°

Angle 5 = 37°
