how did u find the smaller triangle lenght as 2m?

[@TomCassidy001]

because it’s tied to the weight - so if the weight moves 2m (vertically) then the block must also move 2m (along the slope) does that help, or did you have a different question?

[@kenanZ.]

@@TomCassidy001it still doesn’t make sense to me, why did we use 2m as the distance?

[@Undead-wq4vq]

@@kenanZ.that’s how much the 50kg box moves up the slope
