how did he get 70 and 45???

[@lachristechnologies7639]

He didn't give clear explanation.. The angle between two forces becomes the external angle for the triangle and then you can find the internal angle from there... So the angle between Q and the force 50 is 110 which is the external for 50 and Q in the triangle, so to find the internal angle, it forms angle on a straight line which is 180.. Therefore the internal angle is 70

Hallo sorry to bother but im not to sure how did u get the 65* at the second picture (im still quitly very new to this) but further on thank you much bunch for the videos you are a big help much love!

I think it's 180 - 115

[@juliuscuna2238]

You must understand that the sum of triangle is 180 . Thus after getting the first two angles add them (115). Then 180-115 =65.

How did he find 70 and 45

[@troy7788]

since its a straight line and the line moves away at 135 the angle on the other side needs to add with 135 to get to 180 so he does 180-135 to find the missing angle which is 45 and same with the other but with 110
