A triangle drrawn with angles of 40 degrees at the top and 65 degrees on the far right with a measurement of 72 on one side(right side line) sits next too a triangle of a 40 degree angle at the top with a line measurement of 52 on the left side and 45 line measurement on the right side. What would the length of all the missing sides and missing angles be?
