Answer:
45.4°
Step-by-step explanation:
The angle and side lengths in a right triangle are related by ...
Sin = Opposite/Hypotenuse
sin(S) = TU/TS = 3.7/5.2
Using the inverse sine function, we have ...
∠S = arcsin(3.7/52)
∠S ≈ 45.4°
Suppose U= {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P= {1, 2, 3, 4}. What is P?
Digiron [165]
Did you mean P' ? The letter P with a tick mark after it. If so, then start with set U and erase any number you find in set P
We start with
{1,2,3,4,5,6,7,8}
and we erase the following: 1,2,3,4
since those numbers are in set P
P = {1,2,3,4}
P ' = {5, 6, 7, 8}
<span>The set P' is the complement of set P. It is, in a sense, the opposite of set P. It contains everything that P doesn't have.</span>
