Trigonometric identities

What the problems look like

A few statements from this skill. Answers, hints and worked solutions live in the practice session.

1. Warm-up

   Angles $A$ and $B$ are complementary, so $\sin A = \cos B$. If $A = 25^{\circ}$, find $B$ in degrees.

2. Warm-up

   Angles $A$ and $B$ are complementary, so $\sin A = \cos B$. If $A = 55^{\circ}$, find $B$ in degrees.

3. Warm-up

   Angles $A$ and $B$ are complementary, so $\sin A = \cos B$. If $A = 50^{\circ}$, find $B$ in degrees.
