Valerie meat 1 pound of pizza dough. She cut the whole into 12 pieces and then placed an equal number of pieces into packages. She sold one package and had 5/6 of the whole left. She sold another package and had 2/3 left of the whole. How much does the dough in each package weigh? How many packages were made?Explain.

step-by-step explanation:

it's is b

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

yeah i know the problem you need. i am taking it right now. the answer is step 3
