You're right to question the values! However, there seems to be a misunderstanding with the value of B. The value of cosine for any angle must be between -1 and 1, inclusive. -1 1 If B = -(4)/(3), this value is approximately -1.333..., which is less than -1. Therefore, B = -(4)/(3) is not a possible value for the cosine of any angle. Please double-check the problem statement for the value of B. The original problem stated B = -(4)/(5), which is a valid value. Let me know if you have the correct value for B or if you'd like to proceed with the original value of B = -(4)/(5).
