22) Find the measure of angle A to the nearest degree. Find the length of side b, to tenths.

m∠A = 31

b = 13.3

Step-by-step explanation:

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

4+3x is the answer

hope you got it
