I solved it and got 388.21
n + n - 0.18n
We can rewrite it as
2n - 0.18n
And if we solve it
(2 - 0.18)n = 1.82n
So the equivalente expression is B.
The answer is A and B
Because if you look closely it says trucks to SUV's
It says truck first so the trucks would be 7 and the SUV's would be 2
Answer = 127 degrees
Firstly, find out how many degrees in total are in the polygon.
(n stands for number of sides)
(n - 2) x 180
(6 - 2) x 180 = 720
Afterwards, subtract that amount by all the given angles.
720 - 112 - 133 - 128 - 100 - 120 = 127 degrees
Hope it helps :D
