Jeff Friedman was a section chief for an electric utility company. After the numbers in one of his reports to the management of the utility didn't add up, he was reassigned to the home economics department. He interviewed 131 people in a suburban shopping center to discover some of their cooking habits. He obtained the results shown to the right. 52 use microwave ovens; 69 use electric ranges; 52 use gas ranges; 19 use microwave ovens and electric ranges; 21 use microwave ovens and gas ranges; 3 use both gas and electric ranges; 1 uses all three; 2 uses none of the three. Should he be reassigned one more time? Why or why not?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
