Answer:
8
Step-by-step explanation:
The number of days has gone down by a factor of 15/24. The number of workers is inversely proportional, so must increase by a factor of 24/15 = 8/5.
(5 workers) × (8/5) = 8 workers
8 workers are needed to complete the project in 15 days.
In a regular octagon all the interior angles are of the same value.
sum of the interior angles in octagon = (n-2) *180°
n - number of sides, in this case, n = 8
interior angles sum = (8-2)*180° = 6*180° = 1080°
since there are 8 equal angles = 1080/8 = 135°
Angle x + one interior angle of the octagon = 180 ° (as its a straight line)
x + 135 = 180
x = 45°
If you plug the values for a, b, and c into the Pythagorean Theorem, you can get x alone to figure out the side lengths:
x² + 3x² - 1² = 3x² + 1²
Combine like terms
4x² - 1² = 3x² + 1²
Subtract 3x² from both sides
x² - 1² = 1²
Simplify 1²
x² - 1 = 1
Add 1 to both sides
x² = 2
Square root both sides
x = 1.41421
Then, simply plug in that number for x on each side! It comes out to a weird number, but I don't see any other way to solve it...
