What is the sum of the measure of the interipr angles of a 27-gon?

The formula for the total inside angles of any polygon is (n-2)180, where N is the number of sides.

For a 27-gon, replace n with 27 and solve:

(27-2)180 =

25*180 = 4,500 degrees

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
