Answer:
°
Step-by-step explanation:
For the upper left angle, we know that they are supplementary, so we can find the first angle of the triangle by

For the bottom right angle, we know that they are supplementary, so we can find that angle by

As a triangle has 180 degrees, we can subtract the values of the other two angles to find the final upper right angle.

Lastly, The upper right angle and x are supplementary so we can find x by subtracting the angle from 180

Answer:
Hence the degrees of freedom are associated with the critical value is 25.
Step-by-step explanation:
Using two independent samples, two population means are
compared to determine if a difference exists, the population standard deviation is equal.
sample size 1 =
= 15 and sample size 2 =
= 12
since, population standard deviations are equal, required degrees of freedom
