Solve the Proportion: 3/8 = x/12

x = 9/2

Get variable on one side of equation and solve"

x/12 = 3/8

x = (3/8)(12)

x = 9/2

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

21/58.
