I am not sure about the equation...
but...vertical angles are congruent...so < x = < y
< y forms a straight line with 80 and 60.....a straight line measures 180 degrees.....so y = 180 - (80 + 60) = 180 - 140 = 40
therefore, the measure of < x is 40
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:
I think it is A
