One side of a triangle is x inches longer than another side. The ray bisecting the angle formed by these two sides divides the opposite side into 3 inch and 5 inch segments. Find the perimeter of the triangle in terms of x. 10. A student who is 5 feet 8 inches tall casts a shadow of 3 feet. How tall is a nearby tree whose shadow is 27 feet long? 11. A(1,5), B(1,1), D(10,1), E(10,-7). If CE is 10, what are the coordinates of C? A B D C E 12. Using construction tools, divide the segment into 2 pieces that are in a ratio of 2:1. 13.
