solve the triangle for its unkown parts:

ok triangle looks like......
obtuse triangle
with the top point of the triangle is L degrees
and
the middle of the triangle if B degrees
and the last point of the triangle meaning the bottom point is 22 degrees

and then
the two legs of the triangle ..
the standing leg is 50 degrees
and bottom leg is I
and the hypotenuse is 115

---------------------------------------------------------------------------------------
ok i did:

50^2 + I^2 = 115^2
so
115^2 - 50^2 = I^2
13225 - 2500 = I^2
sqrt(10725) = I
103.5615759 = I

ok so i got I
now how do i get L and B...

If its not a right triangle then you can't use that formula.

Is the side shown as 115 opposite angle B?

Is the side shown as 50 opposite the angle shown as 22 degrees?

In any case I think you need to use the sine rule.

a/sinA = b/sinB

Please say which angles are opposite which sides and whether or not the triangle has a right angle shown.
