Konichiwa (hi in japanese , as im clearly an anime fan)
anyways,
We know that, the sum of all angles of a parallelogram = 360°
So, let all the angles be angles P, Q, R and angle S.
Let, <P + <Q = 170°
So, <P + <Q + <R + <S = 360°
=> 170° + <R + <S = 360°
=> <R + <S = 360°-170° = 190° (Ans.)
So, the sum of other two angles becomes 190°
