We know that since a diameter splits a circle in half, the arcs EF, FG, and GH must add up to 180°, half the measure of a full circle. We can then use the arc addition property to create an equation using the information we know. This equation would be (10x + 8) + 67 + 11x = 180. This can be simplified to x = 5. Therefore, the value of x is 5. Now, we can simply plug in the value of x into the expressions for EF and GH. This means that the measure of EF is 58° and the measure of GH is 55°.
Hope this helps!
Figure B is the answer!
The formula for the Pythagorean theorem is
A^2+B^2=C^2
In figure B the units are squared. Making it your answer.

Answer:
Step-by-step explanation:
The heights of young American women, in inches, are approximately Normally distributed with mean μ and standard deviation σ = 2.4. If I want to construct a 99% confidence interval with a margin of error of no more than ± 1 inch, what is the smallest sample I can select?
I believe these are the answers:
1. True.
2. False.
3. False.
4. True.
Let me know if those are right. :)
