I need to see the graphs, can you attach a image of them..
At some point, the exponential function always exceeds a polynomial function.
The answer would be y=-3/4x-3
All angles in a triangle add up to 180 so 180 - 60 = 120 then 180 - 155 = 25 then 25+65 = 90 that is the remaining angle but finally 180 - 90 = 90 is the missing angle
