Answer:
=4x^2−12x+9
Step-by-step explanation:
=(2x+−3)(2x+−3)
=(2x)(2x)+(2x)(−3)+(−3)(2x)+(−3)(−3)
=4x2−6x−6x+9
=4x2−12x+9
We have a right triangle.
Then:
A+B+C=90
Data:
C=90º
A=53º
Therefore:
53º+B+90º=180º
B=180º-53º-90º
B=37º
Answer: B=37º
To check:
Cos 37º=0.79863551...≈0.7986
Answer:
12 ( B )
Step-by-step explanation:
mode means the number that appears the most often
in that case the mode is 12 ( B )
The congruency statement is true TS ≅ HG. so option C is correct.
<h3>What is the congruent triangle?</h3>
Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
Given information;
Triangle G H J is rotated 90 degrees about point X to form triangle S T R.
Triangle GHJ is rotated 90° about point X, resulting in triangle STR.
Now, if any triangle is rotated 90 degrees about a point the two sides will be ≅ to each other.
So, ST = GH
RT= HJ
SR= GJ
<S= <G
<T = <H
<R=<J
The side TS ≅ HG.
Hence, option (c) is correct.
