Answer:
A.
Step-by-step explanation:
14 - (11 + 5) * 3 + 2
Solve inside the parentheses first (11 + 5).
14 - (16) * 3 + 2
Solve multiplication next (16 * 3).
14 - 48 + 2
Solve from left to right.
-34 + 2 = -32
Your answer is -32.
The sum of all angles in an octagon is given by
180*(n-2) >>>>>>>>>with n = 8
180*(8-2) = 1080 degrees
A + B = 1080 .......where
A is the <span>angle of an octagon which is twice that of the other seven angles
</span><span>
B equals the sum of the other seven angles
If we assume each angle of B is equal to each other, then
B = x+x+x+x+x+x+x = 7x
</span>
And A = 2x
The equation that results is
A + B = 2x +7x = 9x =1080
x = 120 degrees
2x = A = 240 degrees
