Question

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

Answer 1

Answer:

x = 7  

Step-by-step 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

( I don't care about your points !)

Answer 2

Answer:

7

Step-by-step explanation:

line in the middle is an angle bisector

14/6 = 21 / 3x - 12

first, cross multiply

14 (3x - 12) = 6*21

Remove the brackets

42x - 168 = 126

Add 168 to both sides

42x = 168 + 126

Combine

42x = 294

Divide by 42

x = 294/42

x = 7
