what is the third side to a triangle if one side is 11 and a second side is 9?

A tree casts a shadow 14 feet long. A flagpole that is 20 feet tall casts a shadow 8 feet long. The triangle formed by the tree and its shadow is similar to the triangle formed by the flagpole and its shadow. Verify that the tree is 35 feet tall.

One angle is twice as large as the smallest angle of a triangle. Another angle is 8 degrees larger than the smallest angle. Find the measures of all three angles of the triangle, listing them from smallest to largest.
