I could answer that for you in a snap if I knew the size of angle 'b'.
Without that information, no answer is possible.
Wait! There is an answer. Not a useful one, but an answer nonetheless.
The cosine of angle 'b' is the square root of [ 1 minus the square of the sine of angle 'b' ] .

If the cosine of angle B is 0.2536 in a right triangle how can I find the measure of ( acute ) angle B with just that information?
Angle of B is cos^-1*(0.2536) = 75.309 degrees to three decimal places
When is secant not defined?
The secant of an angle is the reciprocal of the cosine of the angle. So the secant is not defined whenever the cosine is zero That is, whenever the angle is a multiple of 180 degrees (or pi radians).
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
If the tangent of an angle is 2 what is the cosine?
The cosine is ±1/sqrt(5) = ±0.4472 (approx).
What is the cosine ratio?
In a specific angle for a right triangle the cosine ratio is the ratio between the lengths of the adjacent side (side touching the angle) and the hypotenuse (longest side).
