Question

Here's the rest of my points for anyone who wants them :)

Answer 1

x = 7

Explanation:

"An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle."

so 14 is to 6 as 21 is to 3x -12

14 / 6 = 21/ 3x-12 cross multiply

126 = 42x - 168

42x = 294

x = 7
