The constant of proportionality is equal to k in y=kx. In y=10x, the k value is 10.
Final answer: C. 10
both angles would equal the same so you have:
6x-57 = 2x+15
add 57 to each side:
6x = 2x+72
subtract 2x from each side:
4x = 72
divide:
x = 72/4 = 18
now replace x with 18:
6(18) - 57 = 51
2(18) +15 = 51
51 +51 = 102
Angle QNR = 102 degrees
5x-x=-2-7
4x=-9
x=2/3 or x=-2/3
Since there are 2 answers, it is not one solution.

PERIMETER= AB+BC+CA
AREA = SQUAREROOT
S(S-AB)(S-BC)(A-CA)
S= AB+BC+CA= P
