Statement D must be true. According to the given information, triangles JKM and LKM are congruent and the form triangle JKL, which is an equilateral triangle. That means that angles K, J and L are 60, so angles JKM and LKM are both 30°. This leaves two 30-60-90 triangles, JKM and LKM.

The sale the company must make and sell to break even is;

B=600

<h3>How many helmets must the company make and sell to break even?</h3>

Generally, the equation for the break even is mathematically given as

In conclusion

B=y vertex/price of each

Therefore

B=15600/26

B=600

In conclusion, the company's break even is

B=600

A company plans to sell bicycle helmets for $26 each. The company's business manager estimates that the cost, y, of making x helmets is a quadratic function with a y-intercept of 8,400 and a vertex of (500, 15,900). How many helmets must the company make and sell to break even?
