Answer:
BC = 23
Step-by-step explanation:
Since ∠ A = ∠ C then the triangle is isosceles with AB = BC, that is
3x + 14 = x + 20 ( subtract x from both sides )
2x + 14 = 20 ( subtract 14 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Thus
BC = 3x + 14 = 3(3) + 14 = 9 + 14 = 23

6/10
multiply 3/5 by any whole number ratio equal to 1 to obtain an equivalent fraction.
(2/2)*(3/5) = 6/10
or (3/3)*(2/5) = 9/15
etc.
