The sum of the measures of the three sides of a triangle is 11 cm, and the measure of the largest side is 5 cm, and the smallest side is 2 cm. find the measure of the largest angle.

4.5

Csquared- Bsquared=Asquared

25-4=21

square root of 21 equels 4.5

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
