5.Which of the following statements would give the largest value of theta if theta was less then 90°?

I tried to put number 3 and 4 into a caluculator but the answers were wrong.

I converted (5) to sintheta=4/7 etc, costheta=2/5.. but I don't know how to finish from there

I am completely lost at number 2
