Name:____________________________ Period: ________ Using Triangle Skills to Solve Problems For each word problem below‚ you must draw a picture and show your work towards a solution. Solutions are given for each problem. Since these are real-life type problems‚ answers should be decimal approximations as opposed to being in simplest radical form. You are allowed to use anything you know about triangle similarity‚ right triangles and right triangle trigonometry. This assignment is a learning target
