The sticks of same length are used to form a triangle as shown below.If 87 such sticks are used then how many triangles can be formed?  Select the correct option.
A) 43	B) 44	C) 45	D) 465	E) 47
First triangle is formed by using 3 sticks, but any subsequent triangle may be formed by using 2 sticks. Therefore, If 1st triangles uses 3 sticks, Remaining sticks = 87 - 3=

<output>84</output>
84. With these 84, we can form 42 triangles. So total= 42 + 1=
