The sum of the two angles of the parallelogram is 170 ° to determine the other angles

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,

So,

=> 170° +
=>
So, the sum of other two angles becomes 190°
