Answer:
The answer is:
She used the wrong common denominator
Step-by-step explanation:
Solving the given equation
Lets consider the steps given in the question:
Lets compare both solutions:
In the original solution, the denominator of first term is (x-2)(x-3)
In the solution given in the question, the denominator of first term is (x-2)(x+3).
So the mistake she did in step 2 was that she change the sign of 3 in (x-3) from negative to positive, due to which she gets the wrong common denominator shown in Step 3.

Answer:
c=231.87 m
Step-by-step explanation:
When we read this example we can see that Peter will form triangle with those sides :
a=200 m,
b=180 m
cos X=cos (180-105)=cos75
x is angle.
Now, we can use this rule :
Now, let's evaluate :
<u>Given</u>:
It is given that KLM is a right triangle.
The measure of ∠M is 90°
The length of LK is 89, ML is 80 and KM is 39.
We need to determine the ratio that represents the tangent of ∠K.
<u>Measure of tan ∠K:</u>
The measure of tan ∠K can be determined using the trigonometric ratio.
Thus, we have;
From the figure attached below, the side opposite to ∠K is ML and the side adjacent to ∠K is KM
Hence, substituting the values, we get;
where ML = 80 and KM = 39.
Substituting, we get;
Thus, the ratio that represents the tangent of ∠K is
