it would be 2d - 60

Answer: 1
Step-by-step explanation:
85/7=12 with a remainder of 1
Supplementary means they are equal to 180 so combine them and set it equal to 180.
7x - 2 = 180
Add 2
7x = 182
Divide by 7
x = 26
6/x = x-1
Multiply x by both sides
6= x(x-1)
Set x and x-1 equal to 6
x = 6, x = 1+6 = 7
W=12.
the side across from 31 is also 31, so that’s 62. now 86-62=24, 24 is the remaining length so divide that by 2 because there are 2 sides left and you get 12
