My last question, ? what is value of x? enter your answer in the box. x =

x = 10

Step-by-step explanation:

We can use the Angle Bisector of a triangle and proportions to solve this problem.  Put the smaller triangle over the larger triangle.

AB       x+4

=

AC         2x+1

8       x+4

=

12         2x+1

Using cross products

8(2x+1) = 12(x+4)

Distribute

16x+8 = 12x+48

Subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x +8 = 48

Subtract 8 from each side

4x+8-8 = 48-8

4x = 40

Divide by 4

4x/4 =40/4

x = 10

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
