If one of the exterior angles is 40, you can find its adjacent interior angle by subtracting 40 from 180. This is 40, so the triangle has 2 interior angles that are equal to 40. Now we have 2 of 3 interior angles. The sum of the measures of the interior angles of a triangle is 180, so we can set this equation up:
x + 40 + 40 = 180
x + 80 = 180
x = 100
So the triangle's angles have measures of 40,40 and 100 degrees.

Answer:
Step-by-step explanation:
BC = 20sin(61°) ≅17.5
AC = 20cos(61°) ≅ 9.7
perimeter = 20+17.5+9.7 = 47.2
Answer:
Hence, the probability of exactly 3 successes in 6 trials of a binomial experiment round to the nearest tenth of a percent is:
31.2%
Step-by-step explanation:
The probability of getting exactly k successes in n trials is given by the probability mass function:
Where p denotes the probability of success.
We are given that the probability of success if 50%.
i.e.
also form the question we have:
k=3 and n=6.
Hence the probability of exactly 3 successes in 6 trials is:
Hence,
In percentage the probability will be:
