Answer:
106 degrees
Step-by-step explanation:
Sides AB and CD are equal in length and sides AD and BC are parallel to each other. This tells us that angles B and C are equivalent. Knowing this, we can set up the following equation to solve for x:
Subtract both sides by 42
Subtract both sides by 2x
Divide both sides by 2
Now, to find angle ABC, or angle B, we can plug x back into its expression:
Therefore, the measure of angle ABC is 106 degrees.

8×.25=2
8-2=6
so what you would do is make a bar graph where the y axis would be years and the x axis being height
Step-by-step explanation:
First, find the degrees of freedom:
df = n − 1
df = 49
To find the p-value manually, use a t-score table. Find the row corresponding to 49 degrees of freedom. Then find the α column that corresponds to a t-score of 1.421. You'll find it's between α = 0.10 (t = 1.299) and α = 0.05 (t = 1.677). Interpolating, we get an approximate p-value of 0.084. For a more accurate answer, you'll need to use a calculator.
