If built, the new reservoir will flood a nearby tract of land that is the home to several native species. We Breathe Clean Air (WBCA) members oppose building the new reservoir. They think the council should focus on a campaign of water conservation first. They are preparing their own presentation to the city council. Which graph might the WBCA choose?

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

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

the answer is 13 cm
