Since there is a ratio of 3:2, there must be five equal parts in the whole...
45/(3+2)=9
So each part is equal to 9 inches.
So the shorter piece is 2(9)=18 inches.
Answer:
$43.70
Step-by-step explanation:
90.50 - 4 = 87.50
87.50 ÷ 2 = $43.70

This question has no answer because no angle has a cosine bigger than one.
tan²(<em>x</em>) - sin²(<em>x</em>) = sin²(<em>x</em>)/cos²(<em>x</em>) - sin²(<em>x</em>)
… = sin²(<em>x</em>) (1/cos²(<em>x</em>) - 1)
… = sin²(<em>x</em>) (sec²(<em>x</em>) - 1)
… = sin²(<em>x</em>) tan²(<em>x</em>)
