Alright so these ratios have many different forms but the way I use to remember the trigonometric ratios is:
SOH
CAH
TOA
This means:
Sine --> Opposite/Hypotenuse
Cosine --> Adjacent/Hypotenuse
Tangent --> Oppositie/Adjacent
With that in mind, number 1:
Would be Sine, or C.
Number 2 would be, Cosine, or E.
And number 3 would be Tangent, or B.
Hope that was helpful.
So basically you have to see how the person is built but in average it will took like 12minutes
<u>Answer-</u>
<em>The values of x and y are </em><em>13</em><em> and </em><em>24</em><em>, respectively.</em>
<u>Solution-</u>
From the attachment, l and m are parallel lines and

---------------------1
As, when a traversal line intersects two parallel lines, same-side interior angles are supplementary, or they add up to 180 degrees.

---------------------2
As, an exterior angle is equal to the sum of the opposite interior angles.
Adding equation 1 and 2, we get,
Putting the value of x in equation 1, we get

If they are all 5 dollars then it will be $15
D 8x-3 because must add them all together
