Answer:
Step-by-step explanation:
Use the Law of Cosines to find the measure of angle A from the lengths of the sides.
A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°
B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°
C = 180 - A - B = 95.3°
If we’re talking about the same thing. Determine the shape whether if it’s a prism or pyramid. Then determine what the shape and name of the base.
For example: Triangular Pyramid
Answer:
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
cos(30) = b / c
c = b / cos(30)
c = 5xsqrt(3) / 0.866
c = 10
The probability of Erin not having a heart attack according to her family history would be 30%.
The probability of the test predicting correctly is 67%.
Therefore, the probability of the test correctly predicting that Erin will not have a heart attack would be (0.30)(0.67) = 0.201 or 20.1%.
