We have our A (adjacent), and we want to find our O (opposite), both in respect to the given angle of 50°. Therefore, we will use Tan, (Toa, O and A).

20 * Tan(50)
23.6 to 1DP

Similar concept. In respect to our given angle of 34
°, we have our H (hypotenuse; our longest side, opposite the right angle), and we want to find our O (opposite). Therefore we use Sin (Soh, O and H).

12 * sin(34)
6.7 to 1DP
