8y+4 = 2(y-1)
8y+4 = 2y-2
8y-2y+4 = -2
6y+4 = -2
6y = -2-4
6y = -6
y = -1
The answer is "A. greater than" because if the number of edges increase, the measure of each exterior angle increases too!
Hope this helps. :)
3.8, think of it as 78, which you would round to 80
Answer:
a. 18 b. 119°, 118°
Step-by-step explanation:
a. Given angles are vertical, so they are equal.
6a+11 = 2a+83
6a-2a = 83-11
4a = 72
a = 72/4
a = 18
b. Substituting the value of a in the given angles,
6a+11 = 6*18+11 = 108+11 = 119°
2a+83 = 2*18+83 = 36+83 = 118°
The ratio is 5:1:3 as there is 25:5:15 which is all divisible by 5 making the simplest ratio in that order
