Answer:

  A ≈ 65.4°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...

  Cos = Adjacent/Hypotenuse

  cos(A) = b/c

  A = arccos(b/c) = arccos(2.5/6)

  A ≈ 65.4°
