Answer:
= {2, 4, 10}
Step-by-step explanation:
A set is a collection of objects called elements. These element are refered to as members of the set.
Set A contains all integers from 1 to 10 inclusive;
A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
A subset of a given set implies that every element of the subset are also elements of the given set. Set B is a subset of A;
B = {1, 3, 5, 6, 7, 8, 9}
Complement of a given set refers to elements not in the general set. Set C is the complement of B;
= {2, 4, 10}
A sequence is said to be arithmetic if every couple of adjacent elements differ by the same number. If this is the case, that constant number is called the common difference.
This sequence is arithmetic, because the difference between every element and the previous one is
So, the common differnece is 3.4, because every couple of adjacent terms differ by 3.4
we know that
The measurement of <u>the external angle</u> is the semi-difference of the arcs it includes.
In this problem
Solve for the measure of arc SU
therefore
the answer is
The measure of the arc SU is
