Answer:

[tex]x=27[/tex]

Step-by-step explanation:

Notice that Angle A is being bisected.

Hence, we can use the Angle Bisector Theorem to write the following proportion:

[tex]\frac{x+8}{10}=\frac{2x-5}{14}[/tex]

Solve for x. Cross-multiply:

[tex]10(2x-5)=14(x+8)[/tex]

Distribute:

[tex]20x-50=14x+112[/tex]

Subtract 14x from both sides:

[tex]6x-50=112[/tex]

Add 50 to both sides:

[tex]6x=162[/tex]

Divide both sides by 6. Hence, the value of x is:

[tex]x=27[/tex]
