The measure of the arc KM is 112 degrees. find the measure of the arc LM

so, converting firstly the mixed fractions to improper fractions and then "adding".

here is a big fat

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

2y+y=5

add 2y and y
