In quadrilateral abcd, diagonals ac and bd bisect one another:
what statement is used to prove that quadrilateral abcd is a parallelogram?
angles abc and bcd are congruent.
sides ab and bc are congruent.
triangles bpa and dpc are congruent.
triangles bcp and cdp are congruent.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
