Answer:
21.5?
the more i think the more i believe it
Answer:
Shown Below
Step-by-step explanation:
Alright so first off we are going to use the little 67 on that corner. We know that it's a supplementary angle, and supplementary angles add up to 180.
180 - 67 = 113.
Inside angles of a triangle all add up to 180. Using that we can create the equation:
(x + 27) + x + 113 = 180
simplify.
2x + 140 = 180
subtract 140 on both sides.
2x = 40
divide both sides by 2
x = 20
substitute x into the asked equation.
(20 + 27) = 47
47 is your answer.
The mirror cost when the cpi is 211, to the nearest cent is $187.69
<h3>Ratio and proportion</h3>
Fraction is expressed as a ratio of two integers. For instance a//b is a fraction where a and b are integers.
From the given question, a full-length mirror cost $144.99 when the cpi was 163, hence;
$144.99 = 163 cpi
In order to determine the mirror cost when the cpi is 211, we will write;
x = 211 cpi
Find the ratio;
144.99/x = 163/211
163x = 30592.89
x = 30592.89/163
x = 187.69
Hence the mirror cost when the cpi is 211, to the nearest cent is $187.69
