Hi Guys,
Can somebody answer this for me with the explanation?
I'm not allowed to use a protactor to answer the question.
Thanks.

The triangle is an equilateral triangle -- which also makes it equiangular.
Since there are 180° in a triangle, how many degrees are in each angle? _______
Also, since there are 180° on each side of a line, after you subtract the number of degrees in the angle of the triangle, how many degrees are left for the external angle? ________
