What is the sum of the measures of the exterior angles of an octagon? enter your answer in the box. °

in   this question , we have to find the sum of measures of exterior angle of the octagon.

first we have to find measurement of each interior angle of the octagon, and for that, we use the formula

for octagon, number of sides, n is 8.

so we will get

and sum of interior and exterior angle is 180.

so each exterior angle is

and sum of exterior angles is

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

17   x 256=4352
