Answer : 29.5°
Given r = 10, q = 20, and Q = 100°
From the attached figure we can see that two sides and one angle is given
We use sine rule to find angle R
In triangle QRS
r = 10, q = 20, and Q = 100°
Replace all the values
0.4932403876 = sin (R)
R=![sin^{-1} (0.4932403876)](/tpl/images/0086/0450/367af.png)
R= 29.5 degrees
