5. Matiu is a talented furniture maker and has decided to build a bike frame out of wood. He likes this design he has found online, but instead of curves on the frame, Matiu will use straight pieces of wood. As Matiu intends to use his wooden bike to demonstrate his woodworking skills and promote his business, he will place a triangular sign inside the frame. The sign must have an area of at least 800 cm². He has taken some measurements from his old steel road bike and will use these when he creates his new wooden masterpiece. These are shown below. 15 cm 25 cm 50° 15 cm 30 cm Area inside frame at least 800 cm² 70° Find other crucial dimensions. Hint: In this activity, you are expected to demonstrate the use of the sine rule, the cosine rule and the area of a triangle rule.
