The sum of the interior angle of pentagon is 6x + 6y. Find y in terms of x.
y = 6 - x
y = 90 - x
y = 120 - x
y = 150 - x
Correct answer is B
Sum of interior angles = (2n - 4) 90o
For perntagon, n = 5
Sum of interior angles = 6 x 90o = 540o
6x + 6y = 540o
6(x + y) = 540o
x + y = 540o6 = 90o
y = 90o
y = 90 - x
