The gate will be made with eight of the same vertical boards used for the fence sections, but the gate needs extra bracing to keep it from sagging. Wally will use three horizontal pieces of wood and two diagonal pieces to brace the gate. The horizontal pieces are 28 inches apart. How long should the diagonal pieces be? Round your calculations to the nearest whole inch.

What is the angle measurement between a diagonal piece and a horizontal piece? Round your calculations to the nearest degree.
