Thread: urgent triangle help!

alright i am given the base of a trianlge but no side length, how do i find the height?
the base = 34.64
angle a= 30
angle b=120
angle c= 30

if that helps?
i dont know how to do it and i've been searching everywhere.
please if you can help me and show me how it would be great! (Rofl)

Extend a perpendicular line segment (which is the height) from the vertex to the base. Note that it bisects the base. Then use trigonometry:

isnt that too high of a number for it?
it doesn't seem right?

Yep, it's not right. You made a computation mistake. Recheck it.
