tan²(<em>α</em>) (2 cos²(<em>α</em>) + sin²(<em>α</em>) - 1)

Recall that sin²(<em>α</em>) + cos²(<em>α</em>) = 1 for all <em>α</em>. Then sin²(<em>α</em>) - 1 = -cos²(<em>α</em>) :

tan²(<em>α</em>) (2 cos²(<em>α</em>) - cos²(<em>α</em>))

tan²(<em>α</em>) cos²(<em>α</em>)

Rewrite tan(<em>α</em>) = sin(<em>α</em>) / cos(<em>α</em>) :

(sin(<em>α</em>) / cos(<em>α</em>))² cos²(<em>α</em>)

(sin²(<em>α</em>) / cos²(<em>α</em>)) cos²(<em>α</em>)

Cancel the factors of cos²(<em>α</em>) :

sin²(<em>α</em>)

The perimeter of a rectangular pen is 136 meters. If the length is 5 meters more than twice the width, what are the dimensions o
Sati [7]

Answer: width = 21, length = 47

<u>Step-by-step explanation:</u>

Length (L) = 2w + 5

width (w) = w

Perimeter (P) = 136

P = 2L + 2w

136 = 2(2w + 5) + 2w    <em>substituted the given values above</em>

136 = 4w + 10 + 2w       <em>distributed 2 on the right side</em>

136 = 6w + 10                <em>added like terms (4w and 2w)</em>

126 = 6w                       <em>subtracted 10 from both sides</em>

 21 = w                          <em>divided both sides by 6</em>

Length (L) = 2w + 5

                 = 2(21) + 5

                 = 42 + 5

                  = 47
