Hello :
cos²(θ) +sin²(<span>θ) = 1
(1/4)² +sin²(</span><span>θ) = 1
</span>sin²(θ) = 1 -1/16
sin²(θ) =15/16
sin(θ) = - √(15/16)=- √15/4 because : <span>sin θ < 0.
</span>tan (θ) =sin (θ)/ cos( θ) =(- √15/4)/(1/4) = - √15

We know $65 were spent on his ticket and some shirts.Which he used 32.25 which leaves us with 27.75 and a shirt cost 14 and 50 cent .
SO you need to divide 27.75 in 14 and 50 cents which is equal to
14 plus 14 equals 28
75 plus 50 equals 1 and 25 cents
David can buy two shirts
Hope this helped
