(21x- 19x) -10= 180
2x-10= 180
2x= 190
x= 95
hope this helps!
All angles in a triangle always equal 180 degrees, so to solve this problem you must set 8,3,4 equal to 180. 8x + 3x + 4x = 180. 15x = 180. 180/15 = 12. x = 12. Now you take the value of x and multiply it by the angle you are trying to find. 3(12) = 36.
The measure of the smallest angle is 36.
To check this problem, multiply all the angle ratios by the x value and if it equals 180, it is correct. 8(12) + 3(12) + 4(12) = 180.

Answer:

And from the problem we know the following:
represent the condition if the route is approved
represent the condition if the route is NOT approved
Then replacing in the formula for the expected value we got:

So then the expected number of new employees to be hired by the airline based on the conditions given is between 395 and 396.
Step-by-step explanation:
For this cae we can define the random variable X who represent the number of new employees to be hired by the airline and we can find the expected value with the following general formula:

And from the problem we know the following:
represent the condition if the route is approved
represent the condition if the route is NOT approved
Then replacing in the formula for the expected value we got:

So then the expected number of new employees to be hired by the airline based on the conditions given is between 395 and 396.
