construct a right-angled triangle using the fact that

secQ = 5/4

then secQ = 4/5

adjacent to Q is 4, hypotenuse is 5 ,then

opposite^2 + 16 = 25

opposite = 3

(ahhh, the 3,4,5 right-angled triangle)

so tanØ = 3/4, sinQ = 3/5

The expression I am to verify makes no sense, but after you fix it, the above information will let you determine it.
