I am trying to solve for the height of a right triangle. The base is .05 mm, and the apex is 0.5 degrees. I vaguely recall from high school that this should be enough information to solve for height, but I can't remember what equation(s) to use.

Hi Samantha,

With the help of a little trigonometry this is enough information to find the height.

From the diagram

tan(0.5^{o}) = ^{0.05}/_{h}

and hence

h = ^{0.05}/_{tan(0.5)} = ^{0.05}/_{0.0087} = 5.7 mm
