Find csc B when a - 2 and b = 7
(A detailed answer would be really helpful)
A more complete question, free of typos, would also be helpful.
A figure must go with this question. Is is a right triangle? If so, is C the right angle? Did you mean to write a = 2 instead of a-2? If so, the hypotenuse is 13. That follows from the Pythagorean theorem.
That should tell you what the cosecant is. The sine of angle B would be 7/13. The csc B = 1/sin B
To find the value of csc B, we need to have some additional information. Specifically, we need to know the value of angle B. Without the value of angle B, we cannot directly calculate the cosecant of angle B.
In the given information, you have mentioned that a = -2 and b = 7, but we need the value of angle B to proceed further. If you can provide the value of angle B, we can continue with solving for csc B.
