Question 148148: to the nearest tenth of a degree, how large are the congruent angles of an isosceles triangle that is exactly as tall as it is wide? (There is more than one interpretation.)

Draw it and you'll see that the altitude forms 2 right triangles. The bottom of either right triangle is 1/2 of the altitude.
So, the tangent of the angles on the base is L/(L/2), = 2.
The angle is 63.4 degrees.
