Answer:
α = 20.5
β = 69.5
c = 90
Step-by-step explanation:
we have to make 2 equations one for the relationship between the angles and another for the sum of all the angles
β and α are the acute angles
β = 3α + 8
α + β + 90 = 180
we replace in the second equation the value of β by (3α + 8)
α + β + 90 = 180
α + (3α + 8) + 90 = 180
a + 3a = 180 - 90 - 8
4a = 82
a = 82/4
a = 20.5
now we replace the value of b in the other equation
β = 3α + 8
β = 3 * 20.5 + 8
β = 69.5

See the attached picture to understand how to evaluate the mixed composition of trig functions using a right triangle.
Therefore, the derivative of arccot(x) is
.
The probability of the first item being good is 11/15.
Since we have taken 1 item out the remaining total is now 14, so the probability of getting a defective item is now 4/14.
Now you multiply the probabilities together to get (11/15)(2/7)=22/105

You are adding 40 every time.
The 100th term is 7+(99*40)=3967
