Step-by-step explanation:
User the law of Sines.
![\frac{p}{sin(P)} = \frac{q}{sin(Q)} \\\\\\p= \frac{q*sin(P)}{sin(Q)}](https://tex.z-dn.net/?f=%5Cfrac%7Bp%7D%7Bsin%28P%29%7D%20%3D%20%5Cfrac%7Bq%7D%7Bsin%28Q%29%7D%20%5C%5C%5C%5C%5C%5Cp%3D%20%5Cfrac%7Bq%2Asin%28P%29%7D%7Bsin%28Q%29%7D)
Q = 180 - ∠O - ∠P = 180-59-55=66
Plug in the numbers using the calculator and get 1.7933470905822447027008654200424
Now you need to round it, and you get 1.8 cm
