There's not enough information to find out how long segment CB is or any other segment for that matter.
Sorry I couldn't be of much help.
Answer:
You have 1,435 people in total so you take that number and multiply it by .45 cause there’s 45% male workers and you convert it to a decimal so you can multiply there are 645 male workers since you can’t have 3/4 a human
Step-by-step explanation:
1435 x .45 =645.75
So considering she’s using the Pythagorean Theorem, it implies that it’s a right triangle. In this case, a^2+b^2=c^2 is used to solve for any length. While “a” and “b” are interchangeable, c is always the hypotenuse. And as you may know, the hypotenuse is the longer side of the right triangle.
So now solve for it to be sure if it is in fact a right triangle.
8^2+15^2=17^2
64+225= 289
289=289
Which means B is the error made.
Hope this helps!
The answer is definitely going to be a good day for y’all to do a lot more work
