I'm guessing this is what the question is asking?
In trigonometric ratios, the cos (x) = adjacent over hypotenuse.
Therefore, in the diagram, cos (55°) = s/q
To isolate q, divide both sides by s
cos (55°) / s = 1/ q
Then flip both numerators and denominators (raise both sides to the power of -1)
q = s / cos (55°)

Answer:
£4.59
Step-by-step explanation:
<em>4.38 + 0.45 + 0.58 (0.29 + 0.29) = 5.41</em>
£10.00 - 5.41 = £4.59
