M1 help

Hi. Can someone explain to me how you would get Tsin60 for Question 4 ii)? I don't seem to get how you would get Tsin60 from the diagram. I think I'm just being really stupid and missing an obvious angle rule but I would appreciate some help. Thanks.

What did you get as the component of T parallel to the slope?
