I need to go to sleep get my stuff out
abcd is a parallelogram
Step-by-step explanation:
so yiu gotta like 1 angle to the 2 angle buy thats seprare from the 3 angle to the 4 angle
Sin (tan^(-1)X)
Sin (1/tan X)
Sin (1/1 / tan X/1)
Tan X = sin X/cos X
Sin (1/1 / sin X/cos X)
Sin (1/1 • cos X/Sin X)
Sin (cos X/sin X )
Cos X.
I believe the correct answer is cos X.
