A student said that m<1=80 degrees. what error did the student make
Answers
The error the student made is referring to an angle, m<1, being equal to 80 degrees. It is incorrect to assign a measurement or value to an angle without any given information or reference point.

ii. A CD
Answers
Answer:
One book equals $8 and one CD equals $5
Step-by-step explanation:
Let books be denoted as 'x' and CDs as 'y'
5x + 2y = 50 ...1
2x + 3y = 31 ...2
I usually eliminate the y variable, and to do this, you multiply the first equation by 3 and the second equation by 2, because the lowest common multiple between 2 and 3 is 6.
...1*3 and ...2*2
15x + 6y + 150 ...3
4x + 6y = 62 ...4
Eliminate y by taking ...4 away from ...3
15x - 4x = 150 - 62
11x = 88
x = 8
Sub this value into ...1
5(8) + 2y = 50
40 + 2y = 50
Rearrange
2y = 50 - 40
2y = 10
y = 5
This means that one book is $8 and one CD equals $5
Answer:
Book = $8 each
CD = $5 each
8 x 5 = 40
2 x 5 = 10
= 50
8 x 2 = 16
5 x 3 = 15
= 31

What is Algebra?
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The exponential expression is given as,
⇒ (4)⁵
In the exponential expression aⁿ, the n is the exponent or power and a is the base of the expression.
Then in the exponential expression (4)⁵, the number 5 is the exponent or power and the number 4 is the base of the expression.

Answer:
D.SSS Congruence is correct
Final answer:
Without more information, any of ASA, SAS or SSS could potentially prove that △ABC ≅ △BAD. AAA cannot, since it proves only similarity, not congruence.
Explanation:
To determine whether the triangles △ABC and △BAD are congruent, we would need to apply one of the known congruence theorems. This could be the ASA Congruence theorem, the SAS Congruence theorem, or the SSS Congruence theorem.
The AAA Congruence theorem, however, cannot be used to prove triangle congruence. It is important to highlight that it only proves similarity, not congruence.
From the given options, we need to know the exact measures of the angles and sides for △ABC and △BAD to choose the correct theorem to apply. Without any additional information, any of the options ASA, SAS, or SSS could potentially be used.
