Question

solve for theta: sec theta = csc (2 theta - 15)

please help! desperateeee

Answer 1

Since sec =1/cos and csc=1/sin by flipping the equation we have
cos(theta)=sin(2theta -15)
Can you solve that now?

Answer 2

i dont know how to solve it though. but i understand what you just said. could u explain the next step?

Answer 3

firs is the problem \(sin(2(\theta-15))\) or \(\sin(2\theta-15)\) ?

Answer 4

csc (2θ−15)

Answer 5

Remember that \(cos \theta =\sin(90-\theta)\)

Answer 6

So one of the solution can be obtain by setting
\(90-\theta =2\theta -15\)

Answer 7

ok so i got 105 = theta...is that the answerr?
