Hello all,

I've been out of high school for many years and just started Trigonomtry and cannot fiqure out this problem to save my life. I would appreciate any help. Thank you in advance

In isosceles (picture a triangle)ABC, AB +AC, (picture a angle)C = 70 degrees, and BC = 4.0 cm.

calculate the height of the triangle to the nearest millimetre

Does anyone have any ideas?

I fiqured out the problem: 70 TAN = 2.7474 X 2 = 5.5 to the nearest millimetre. Apparently there's two right angles in an isosceles. Thanks anyways
