There is no graph and I need the measures of the four angles.

you just switch the numbers basically so it would be 3/17

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
