1) corresponding pair <4 and <12
answer is a
2)
<2 = 133 (corresponding)
<2 = <5 = 133 (vertical angles)
answer a . 133
²⁰¹²C₂₀₁₁ = (2012)! / [(2011)! (2012-2011)!]
²⁰¹²C₂₀₁₁ = (2012)! / [(2011)! (1)!]
Simplify 2012! / (2011)! = 2012
²⁰¹²C₂₀₁₁ = (2012)! / (1)! = 2012
I dont understand what u writing?
4) x*2x=
2x^2
9) 5x+2*x+3=
5x^2+17x+6
i think these are right lol gl
Mathematical proofs are used to determine if a conjecture or statement is true, or otherwise.
The blanks will be filled with the following texts
- Given
- Proved
From the question, the following parameters are given:
and
This means that, the first blank will be completed with given.
By converse of alternate interior angles theorem
--- angle 1 and angle 2 are congruent
So, the second blank will be completed with
The above statement means that:
has been proved
Hence, the last blank will be completed with proved.
