1. The problem statement, all variables and given/known data Given that (csc a) = (sec0.75) and that 'a' lies in the second quadrant, determine the measure of angle 'a', to two decimal places. 2. Relevant equations reciprocal and quotient identities. 3. The attempt at a solution I only got as far as: 1/sin(a) = 1/cos(0.75) The answer in the back of the book is 2.32 Can anyone guide me towards the light? thanks in advance!
