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

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
