every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
a - base
b - exponent
so,the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
We know if we try to divide 15 with 8 we would have to give away 1.875, if that isn't what you mean please let me know and I will make sure to solve it!
