Sum of all the angles in a triangle is 180°.
Therefore in ΔQRS,
R + S +Q = 180°
61° + 29° + Q = 180°
Q = 180 - 61 -29
Q = 90°
Hence option A is correct.
Hope this helps, have a nice day!
The answer is b. Notice that the problem is looking for the reaction to product ratio, which is tricky because it's easy to follow the order of the column and calculate the inverse of it. Check the first ratio, 0.3/2=0.15, we can immediately choose b out of the other 4 choices.
