8. catgirl17

9. catgirl17

.72654

10. hartnn

as we know tan 36 = 36/x so x= 36/ tan 36= 36/ 0.72654 = ??

11. catgirl17

where you have the other 36 wouldn't that be a 12?

12. hartnn

the opposite side to 36 degree angle is 36, right ??

13. catgirl17

shouldn't it be 12

14. hartnn

tan 36 = (opposite side)/(adjacent side) opposite side = 36 adjacent side = x ok?
