Answer:
162 degrees
Step-by-step explanation:
Angles P and F are supplementary, so ...
3x^2 +12x = 180
x^2 +4x = 60
x^2 +4x -60 = 0
(x +10)(x -6) = 0
The useful value of x that makes this true is x=6.
The measure of angle Q is 3x, so is 3·6 = 18 degrees. The measure of angle S is the supplement to that:
∠S = 180° -18° = 162°
Answer:
100 over 9
Step-by-step explanation:
The toughest part of this is to figure out exactly how to express that complex formula description.
You begin by writing the equation form as it is in written in English, the important words there are the 'whole' ones... which means to close the parenthesis.
Once you have written it all out as shown on the first line of the attached image, you just have to do the calculations, as demonstrated in the other 3 lines.
