An 11-inch string is cut into 3 equal pieces. which expression shows the length of each piece?

11.6666 11 divided by3 equals 1.6666

That previous answer is wrong because that would mean you only have about 5 cm. The equation should be 3(x) = 11. then you divide it from there and should get about 3.66666666 for each strip

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
