Which of these data sets is symmetrical? A. 1, 6, 11, 16, 16, 16, 21, 21, 21, 26, 31
B. 1,1, 11, 11, 16, 16, 16, 21, 21, 26, 31
C. 1, 6, 11, 11, 16, 16, 16, 21, 21, 26, 31
O D. 1,6, 11, 11, 11, 16, 16, 16, 21, 26, 31

c is the correct answer I'm pretty sure. it is equal to 32 when adding both sides

60 for the first and 130 for the second

step-by-step explanation:

can someone me: the midsegment through the legs of an isosceles triangle is 4 in. find the sides of the triangle if its perimeter is 20 in. ,   and point g is the centroid of the right △abc with hypotenuse ab=18 in. find cg.
