I am extremely lost on this problem. Please help!

4. London misplaced his 14mm wrench, so he is 3D printing a replacement, just a card with a regular hexagon-shaped hole (regular means that the sides are all the same length). The 14mm of a hex wrench is the distance from one flat side to the flat side opposite; however, London's 3D printing software requires the distance from one vertex (corner) to the opposite vertex. (a) Draw a diagram of this scenario. Label the 14mm and the distance London needs to calculate. (b) Find the distance that London needs for his design. Round your answer to the nearest tenth of a mm. SHOW YOUR WORK. Hint: If you connect each vertex with its opposite, then you have divided the hexagon into six triangles. What has to be true about the angles of those triangles
