This is the concept of algebra, the denominator of y+(y-3)/3 will be as follows; the expression y+(y-3)/3 can be written as: y/1+(y-3)/3 the denominator of the first term is 1 and that of the second denominator is 3, to get the common denominator for both terms we multiply both denominators; thus the common denominator will be: 3*1=3 thus the our common denominator will be 3:
Step-by-step explanation: So the question here is only asking for one angle, so you take the sum of all of the angles (835) and divide it by the total amount of sides (8). and you have your answer.
