Angle x is in the first quadrant and angle y is in the second quadrant, such that Cosx = 12/13 and Siny = 7/25. Determine an exact value for Cos(x+y).

Find the area between y=e^x and y=e^2x over [0,1]

Pleas ! i just cant seem to get it right! choose: congruent or proportional choose: cf or ce or bc choose: segment addition postulate or cpctc
