Answer:
x = 10
Step-by-step explanation:
Here, we are tasked with calculating the value of x.
To do this, we need the picture of the wordings given in the question.
please check the attachment for a pictorial representation.
Now the theorem to use is that , the exterior angle of a triangle is equals the sum of the two opposite interior angle.
Thus, mathematically;
3x + 11 + 3x + 15 = 10x -14
6x + 26 = 10x -14
10x-6x = 26 + 14
4x = 40
x = 40/4
x = 10

<h2>
Option B is the correct answer.</h2>
Step-by-step explanation:
Let w be the work and r be the rate at which one machine is doing the work.
The amount of time needed by the 10 machines, working together, to complete the job is 16 hours.
Work done by machine = Number of machines x Rate at which one machine is doing the work x Time
w = 10 x r x 16
Now we need to find time taken t by 8 machines to the same work.
Work done by machine = Number of machines x Rate at which one machine is doing the work x Time
w = 8 x r x t
Time taken 8 machines to the same work = 20 hours
Option B is the correct answer.
20 • 12 is 240
1/2 • 12 • 4 is 24
so 264
