Answer:

sum of interior angles of octagon is 1080 degrees

From figure ,

136 + 132 + 129 + 116 + 158 + 141 + 124 + x = 1080

so, x = 1080 - 936

        = 144

Step-by-step explanation: Simply add the angles and substract the sum from 1080 which is the sum of interior angles of octagon

Answer:

144 degrees.

Step-by-step explanation:

There are 8 sides to this polygon so the total internal of

angles = 180( 8 - 2)

= 1080

Adding up the 7 given angle we get  936

So x = 1080 - 936

= 144.
