Step-by-step explanation:
measure of the exterior angle of triangle equal to the sum of 2 interior non adjacent angles
The answer would be C. a > 2
If a > 2, then a could = 3
n = 3*3 - 6
n = 9 - 6
n = 3
3 is a positive number
For this one I'm going to assume that 4 7a means 4 * 7a...
(8 + 7a) + 4 * 7a =
8 + 7a + 28a =
8 + 35a
If I read it wrong and 4 7a is actually 47a then...
(8 + 7a) + 47a =
8 + 54a =
2(4 + 27a)
