The two equal sides of an isosceles triangle are each 36cm. If the base measures 30cm, find the height and the measure of the two equal angles.
I was able to solve the problem completely but of the answer choices I was not quite sure because they did not match up completely:
either a.The height is 33cm; the angles are 65 dgrees. or b. The height is 33cm; the angles are 67 degrees.
I came up with the angles being 66.4 degrees which would be 66 degrees using the sin method and the other being 24.6 degrees which would be 25.6 degrees. So I was thinking the answer would have to be a?
