This is a theorem called Converse of Alternate Exterior Angles that states that <em>if two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel</em>. Moreover, this theorem is based upon the corresponding Angles Converse Postulate that states that<em> if two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel. </em>We don't need to prove this postulate, it's assume to be true. So our goal is to get corresponding angles congruent in order to use the corresponding Angles Converse Postulate,

Reason: Given

Statement: $\angle1\cong\angle2$

Reason: Def of vertical $\angle s$

Statement: $\angle1\:and\:\angle3 \ are \ vertical$

Reason: Def of vertical $\angle s$

Statement: $\angle1\cong\angle3$

Reason: Transitive Property

Statement: $\angle2\cong\angle3$

Reason: corresponding Angles Converse Postulate

Statement: $p\parallel q$

Identify the percent increase in total sales and the percent increase in sales of trench coats. Then find which percent of

Ilya [14]

Answer:

Answer b: Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

First add all the sales for 2006, and do the same for the 2007 sales, so we can compare both total sales numbers:

For 2006 we have:

103+297+210+213+137 = 960 total sales

For 2007 we have:

127+223+210+285+259 = 1104 total sales

The percent increase is calculated as the difference between the final value minus the original value, divided by the original value and multiplied by 100:

For the total number of coats we have that the percent increase is: $\frac{1104-960}{960} * 100= 15$ %
