Step-by-step explanation:
ASA and AAS cannot be used because we can only confirm one angle of each triangle.
Congruent shapes have equal corresponding sides and angles.
The congruence theorems that can be used to prove [tex]\triangle ABR \cong \triangle ACR[/tex] are HL, SAS, and SSS
[tex]\triangle ABR \cong \triangle ACR[/tex] means that, the triangles are congruent.

Answer:
1) response b
2) x=35 (response c)
3) response d
Step-by-step explanation:
1) The Pythagorean theorem's "C" value is the value of your hypothenuse, which means that it would be c^2-b^2=a^2
You would set it up as "7^2-4^2", and then to get rid of the squared value, you would have to square root it
2) In this question, you're finding the hypothenuse, therefore the two values given are your "a" and "b" values.
[tex]\sqrt{21^{2} +28^{2} } =x[/tex]
[tex]\sqrt{441+784}=x[/tex]
[tex]\sqrt{1225} =x[/tex]
x=35
3) This is pretty much self explanatory if you know the C value is the hypotenuse
[tex]\sqrt{4^{2}+5^{2} }[/tex]

Rearrange the equation
a = 1/2 (b-c)
to make b the subject.
Answers
Answer:
b = 2a + c
Step-by-step explanation:
Given
a = [tex]\frac{1}{2}[/tex] (b - c)
Multiply both sides by 2 to clear the fraction
2a = b - c ( add c to both sides )
2a + c = b
After the rearrangement, the equation as b the subject b = 2a + c.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given that the equation;
a = 1/2 ( b - c)
Rearranging the equation;
a = 1/2 ( b - c)
Multiplying 1/2 to the the terms of brackets,
a = (b/2) - (c/2)
b/2 = a + (c/2)
Divide by 2 on both sides of the equation;
b = 2a + c
Therefore, the equation as b the subject b = 2a + c.

at first glance, you would agree that a # to the third power would be greater, however, when the base is a negative #, the result is a negative and smaller #.
for example, 3^3 = 27 but if it is -3^3, the answer is -27.

There are 15 books on a shelf. 8 of these books are new. The rest of them are used.
(a) What is the ratio of used books to all books on the shelf?
(b) What is the ratio of new books to used books?
Answers
Answer:
a. 7:15
b. 8:7
Step-by-step explanation:
there are 7 used books and 8 new books, thus, there are 15 books on a shelf.
(a) The ratio of used books to all books on the shelf is [tex]\dfrac{7}{15}[/tex].
(b)The ratio of new books to used books is [tex]\dfrac{8}{7}[/tex].
Given that:
Total number of books = 15
Total number of new books = 8
Total number of used books= 15-8
= 7
(a) The ratio of used books to all books on the shelf is calculated as:
Ratio = [tex]\dfrac{ Used \ books}{ Total \ books}[/tex]
= [tex]\dfrac{7}{15}[/tex]
(b) The ratio of new books to used books is calculated as:
Ratio = [tex]\dfrac{ New \ books}{ Used \ books}[/tex]
= [tex]\dfrac{8}{7}[/tex]
Thus, the ratio of used books to all books on the shelf is [tex]\dfrac{7}{15}[/tex] and the ratio of new books to used books is [tex]\dfrac{8}{7}[/tex].
