Triangles. Thank you for your helps. Next question now.?

Question

And this is not homework, please don't patronise like that. I am making a thing and I don't have the trig. (But I do have Yahoo Answers!)
Now the next triangle is a iso also and has the unequal side at 5.62mm and the 2 equal angles at 8.5 degrees. Please, I need the length of the two equal sides and also if a you drop a perp from the third angle to half-way along the known side, how long would that be? Thanks.

Answer 1

(5.62/2)/L = cos(8.5°)
L = 2.81/cos(8.5°)
L ≈ 2.8412 mm

h/2.81 = tan(8.5°)
h = 2.81tan(8.5°)
h = 0.41996 mm ≈ 0.42 mm
