how many triangles can be made with 87 sticks which is of the above form?

• in the given 1 tringle is already formed u dont mention it then after making a tringle with 3 stick then in continous it needs only 2 stick to formed the tringle then 87-3=84 tringle is there so 842=42 stick are used but 1 is already formed by 3 stick so it is 42+1=43

• simply use this formula:-
  2n+1=87
  2n=87-1
  2n=86
  n=43.
  Hence 43 no of triangle can be made by the 87 sticks.

• To solve questions like these, use formula, 2n + 1 = k. Here n = triangles, k = sticks
  2n+1 = 87 ⇒⇒ n = 43.

• Ans=43 triangles
  total 87 sticks
  one(1) triangle is formed by 3sticks.----(1)
  87-3=84sticks
  so remaining 2 sticks are formed 1 triangle=84/2=42 triangles /_
  so total /_ are formed 42+1=43 /_
