Hi there!
Let's go through each option one-by-one.
A - Angle 1 cannot be equal to angle 3 because it is given that they are complementary. This option is INCORRECT.
B - Angle 2 and angle 3 cannot be supplementary because they are both less than 90 degrees. This option is INCORRECT.
C - By the substitution property, angle 2 would be complementary to angle 3. Since angle 1 equals angle 2, and we know that angle 1 is complementary to angle 3, we can substitute in angle 2 for angle 3. This option is CORRECT.
D - Angle 2 is not equal to angle 3 because in the given it states that angle 2 is equal to angle 1. This option is INCORRECT.
Therefore, the correct answer is option C.
Hope this helps!! :)
