Answer:
Given the expression: 
Let the value of the given expression in radians be 
then;
......[1]
We know the value of 
Substitute the given value in [1] we have;
Since, the value of 
is 0, therefore, the value of is in the form of:
; where n is the integer.
At n =0, 1 and 2, {Since, n is the integer}
Value of 
and 
therefore, the answer in radians either 
or
Now you can see its pretty simple, its 128 but the way i got it is first you double 8 which makes 16 right then double 16 and you can see you got 32 then double 32 which makes 64 so next what you have to do is double 64 Obiously so you just double those numbers to get 128....Get it?

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
