The correct answer is 1/a^7 (b)
So you know all angles in a triangle add to 180 degrees and you have x + 3x + 2x which adds to 6x so you do 180/6 to get x = 30 and c = 2x so you do 30 x 2 which is 60 degrees. Hope this helps :)

Answer:
x= -9 y= 7
Step-by-step explanation:
Answer:
15, 8, 13, 13
Step-by-step explanation:
(1) mean = Σx / n = 135 / 9 = 15
(2) range = highest value - lowest value = 21 - 13 = 8
(3) mode = 13 (most repeated value in data set)
(4) for 9 values in a data set, we have that (9 + 1) / 2 = 5th number
median = 13
