m∠B=144°

Step-by-step explanation:

see the attached figure to better understand the problem

we have

Two parallel lines cut by a transversal.

so

m∠A=m∠B -----> by alternate interior angles

substitute the given values and solve for x

Find the measure of m∠B

m∠B=(6x+72)°

substitute the value of x

m∠B=(6(12)+72)°=144°

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
