determine the measure of <1 and <2 using 14x-15 please help

To determine the measure of <1 and <2 using the expression 14x-15, we need more information.

It seems like <1 and <2 are angles, but we don't know if they are related to each other or to the expression 14x-15 in any way.

If you have any additional information or context, please provide it so that I can assist you further.
