Answer:
answer is - 95, 40, 45
Step-by-step explanation:
Since the interior angles of a triangle add up to be 180 degrees, I set up the equation like so:
(8x-1)+(3x + 4)+(3x + 9) = 180
=> 14x +12 = 180
=> 14x = 180-12
=> x = 168/14 = 12
now putting value of x = 12
we get---
8*12 -1 = 96-1 = 95
3*12 + 4 = 36+4 = 40
3*12 + 9 = 36 + 9 = 45
( Answer )
B
Because C, Is greater than, X.
8a + 9b and 16a - 10b
you would just 4.8 x how many years
