not sure just what you're after, but
6/25 - 4/5 = 6/25 - 20/25 = -14/25
6/25 - 4/5 = 6/25 - 20/25 = -14/25

I need help for this question,
From the top of an 8m house, the angle of elevation to the top of the school’s flagpole across the street is 9 degrees. The angle of depression is 42 degrees to the bottom of the pole. How tall is the flagpole?

you should post your own question, not piggyback on someone else's where it might get lost.
Draw the diagram and review your basic trig functions. It should be clear that if the pole's height is h, then
8 cot42° = (h-8) cot9°
Now just solve for h
