You have the correct idea for the boxes you've filled out. For the first three boxes in column 1, I would be specific which segments you are dividing. So for instance, in the first box, it would be EG/EB = 55/11 = 5. Then the second box would be EF/EC = 35/7 = 5, and so on. The order of the boxes doesn't matter. The three boxes then combine together to help show that the triangles are similar. Specifically . The order of the letters is important to help show how the angles pair up and how the sides pair up. We use the SSS similarity theorem here.
The second problem is the same idea, but we use one pair of congruent angles. So we'll use the SAS similarity theorem this time.
Barry found a computer at Staples for $989. A week later, the computer went on sale for $849. The percentage change is 14.156 % decrease
<em><u>Solution:</u></em>
Given that Barry found a computer at Staples for $989
A week later, the computer went on sale for $849
To find: percent of change
Percent change is the extent to which a variable gains or loses value. The figures are arrived at by comparing the initial (or before) and final (or after) quantities according to a specific formula.
<em><u>THE PERCENT CHANGE IS GIVEN AS:</u></em>
If the result is positive, it is percentage increase
If the result is negative, it is percentage decrease
Here initial value = 989 and final value = 849
Substituting the values in above formula,
Here negative sign denotes percentage decrease
Thus percentage change is 14.156 % decrease
