ANSWER

EXPLANATION
Vertical angles face each other directly opposite just like the angles formed on the opposite sides of the letter X.
Vertical angles, also called vertically opposite angles are equal.
From the above diagram,

because they are vertically opposite to each other.
The correct answer is B.
Answer:
=> 6s
Step-by-step explanation:
Given terms
24s^3 ,12s^4 and 18s
GCF consists of the common factors from all the terms whose GCF has to be found.
In order to find GCF, factors of each term has to be made:
The factors of 24s^3:
24s^3=2*2*2*3*s*s*s
The factors of 12s^4:
12s^4=2*2*3*s*s*s*s
The factors of 18s:
18s=2*3*3*s
The common factors are(written in bold):
GCF=2*3*s
=6s
So the GCF is 6s ..
Answer:80students
Step-by-step explanation:
Using set notation concept,
n(U) be the total number of student = 200
n(AnS') be those that earned Bachelor in Art only= 120
n(A'nS) be those that earned Bachelor in Science only= 40
n(AnS) be students that earned both degrees.
Using the formulae below to calculate n(AnS) first;
n(AuS)=n(A'nS)+ n(AnS)+n(AnS')
200=40+n(AnS)+120
200=160+n(AnS)
n(AnS)=40
This shows that 40students earned bachelor in both degrees
Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.
NB: A' means complement of A(A not included)
'n' denote intersection and 'u' denote union.
