Hello, welcome to lead on that may be able to see any quadrilateral EQ is is also given the angle T is to angle Q is to angular speed is going to be ratio 3 is to forge 267. The ratio is given as 3 is to 4 is 2 6 is 2 7. Okay. Okay. I tried each angle of the coordinates and then product p q and Sarah are going to be parallel to each other and PS also panic in Cuba. That's about it. Sweet is going to be in the form of will check it out. You can take it as a season 3 egg place. So Eric's place 6X plus 7 x is going to be 360. Okay. So when you calculate this Bolsa Queen DX is going to be 360. Sadly it. Okay, it's not going to be parallel. Okay, so I hope you understood this video. So p is n QR are not parallel, so please subscribe to our channel for more interesting and updated videos. Thank you so much for watching this video and let me know in the comment section if you have any doubts. Thank you.
