You do not have to draw another diagram. The 8 cm is opposite angle x - Do you see that ?

OpenStudy (anonymous):

yes

OpenStudy (wolf1728):

Now what side is adjacent to angle x (remember not to choose the hypotenuse)

10

OpenStudy (wolf1728):

No - ten IS the hypotenuse. How much trigonometry have you studied? This opposite adjacent hypotenuse side is VERY fundamental.
