The measure of 13 angles of a 14-gon add up to 2014. What’s the fourteenth angle measure?

146

Step-by-step explanation:

sum of measures of the interior angles of any polygon u can get by the rule (n - 2) * 180.

in which n is the number of sides

so u replace the n with 14 and u get 2160 and the sum of 13 of the angles are 2014 .

so u subtract 2160 with 2014 and u get your answer

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

this is answer of 144 cubic meters
