Answer 1

"In an isosceles triangle, two sides are equal in length.[2][3] An isosceles triangle also has two angles of the same measure; namely, the angles opposite to the two sides of the same length; this fact is the content of the Isosceles triangle theorem."

AND

"In Euclidean geometry, the isosceles triangle theorem, also known as the pons asinorum, states that the angles opposite the two equal sides of an isosceles triangle are equal. It is, in essence, the content of proposition 5 in Book I of Euclid's Elements."

-Wikipedia.

Now, given that a triangle's angles add up to 180 degrees and both of the missing angles are equal, I think you'll be able to solve it :)
