I have made two errors on each of these problems, and I am given one more chance to get these answers correct. May you please explain where I am going wrong?

Thank you so much!

Find the measure of angle x, if possible. Notice that X is an obtuse angle. Round to the nearest tenth. (If not possible, enter IMPOSSIBLE.) 30 26 A pole leans away from the sun at an angle of 5 to the vertical, as shown in the gure below. When the elevation of the sun is 56", the pole casts a shadow 45 feet long on the level ground. How long is the pole? Round to the nearest tenth. 0 c5 Assume a is opposite side a, is opposite side b, and y is opposite side c. If possible, solve the triangle for the unknown side. Round to the nearest tenth. (If not possible, enter IMPOSSIBLE.) p = 56.4, a = 10.2, c = 13.7
