In the figure, angle K measures 45 degrees. What is the measurement of angle C?

Delvig [45]

It is 45 because the triangle should be 180 degree and if K is 45 then J should be 45, too. We all know that the right triangle is 90 degree, so we add angle J and G, it is 135. Lastly, you subtract 180- 135=45.
