m∠P+m∠R=180 degrees (2x+10)+(x+20)=180 3x+30=180 3x=150 x=50 m∠P=2x+10=2(50)+10=110 m∠R=x+20=50+20=70 Because ∠Q and VS are supplementary m∠Q+m∠S=180 (2y)+(3y-20)=180 5y-20=180 5y=200 y=40 m∠Q=2y=2(40)=80 m∠S=3y-20=3(40)-20= Final Answer=100
um do not give them the direct answer
Hint: The sum of the measures of the interior angles of a quadrilateral is \(360^{\circ}\)
So. Am I correct. Or Incorrect. Lol
Second Hint: \(m\angle{P} + m\angle{Q} + m\angle{R} + m\angle{S} = 360^{\circ}\)
OKay Got it Ty
@jhonyy9
Third Hint: \(m\angle{P} = 2x+10\)
So yes. I'm correct..
Hero. You are making me reach a whole new level or confusion XD
Where are you confused? Add all the expressions together that represent the 4 angles, set it equal to 360 then solve for x. That's the first step. Substitute the value found for x in each expression to find the measure of each angle.
Ohhhhhhh. Okay that clarifies it. Thank you!
Actually, I realize that the variables are different. It has to be done a different way.
The adjacent angles sum to 180 so \(m\angle{P} + m\angle{Q} = 180\) \(m\angle{Q} + m\angle{R} = 180\) Insert the expressions in place of each angle, Then solve as a system of equations

I did the problem again. I got the same answer. When I turned it in it was also correct.
