Question

What is the value of x

Answer 1

Answer:

x=5

Step-by-step explanation:

We can use the Triangle Angel Bisector Theorem

AB             2x-1

----------= --------------

AC               3x

9              2x-1

----------= --------------

15               3x

Using cross products

3x*9 = 15*(2x-1)

Distribute

27x = 30x-15

Subtract 30x from each side

27x-30x = 30x-30x-15

-3x = -15

Divide by -3

-3x/-3 =-15/-3

x =5
