53) Vertical angles are congruent, so m\angle IDA=121^{\circ}

54) \angle YDA and \angle YDF are supplementary, so m\angle YDA=180^{\circ}-121^{\circ}=59^{\circ}

55) Because vertical angles are congruent, m\angle FDI=59^{\circ}. Now, because DR bisects \angle FDI, this means m\angle RDI=\frac{59}{2}=29.5^{\circ}

56) This is a geometric sequence where the next term is obtained by multiplying the previous term by -2, so the next two numbers are 16, -32

This number is rational. It wouldn't be rational if the digits won't repeat.

This is irrational. The digits of pi do not repeat, making it irrational.

Fifth:

  • -√14

Irrational. The square root of a non-perfect square is irrational.
