Answer 1

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°
