<9 and <10 are corresponding and complementary angles formed by two parallel lines cut bye transversal. Find m<9

42

To find the measure of angle <9, we need to use the fact that <9 and <10 are corresponding angles formed by two parallel lines cut by a transversal.

Since the lines are parallel, we know that corresponding angles are congruent. So, the measure of <9 is equal to the measure of <10.

Let's assume that the measure of <10 is x.

Therefore, the measure of <9 is also x.

To find the value of x, we need additional information or measurements provided in the question or figure. If there are no additional measurements given, we cannot determine the exact measure of <9.
