stuck on only these "easy" geometry questions?
i finished all the other problems but i couldnt figure out how to do these, even by reading the chapter over and over. please show me HOW you got these:1. If x and 3x  10 represent the measure of the acute angles of a right triangle, find the value of x. show all work.2. A regular polygon has 12 sides. Find the measure of each exterior angle. show all work.3. Four of the angles of a pentagon have measures 30, 70, 120 and 165. Find the measure of the fifth angle. show all work.
