Hi, thank you for posting your question here at Brainly.
All you have to do is add all the angles and equate to the total sum of angles for a quadrilateral.
360 = Angle Q + Angle P + Angle R + Angle S
Other relationships/equations are:
Q = 2P
R = 3b-19
S = 3b+10
Then, substituting...
360 = 2P + P + 3b - 19 + 3b + 10
360 = 3P +6b - 9
360 - 3P + 9 = 6b
6b = 369 - 3P
b = (369 - 3P)/6
b = 61.5 - 0.5P
Once you know the value of P, then you can determine the exact value of b.
Because most countries involved in the war had alliances with others. And when one was attacked the ally came to protect the other. Therefore countries became more and more involved in the war
