1. Calculating Cosecant, Secant, and cotangent
Adapted from Walch Education

2. Remember: Cosecant is the reciprocal of sine. Given the angle
Secant is the reciprocal of cosine. Given the
Cotangent is the reciprocal of tangent. Given the

4. Based on the given information, we must use the secant function, the reciprocal of cosine.
Secant is the reciprocal of cosine. This means that

5. x ≈
Since most calculators do not have buttons for the reciprocal functions, you will have to substitute this value in the expression in order to correctly calculate the value of x.
