Answer:
108° and 72°
Step-by-step explanation:
let one angle be x then the other angle is 
x
the sum of the 2 angles = 180°, hence
x + x = 180 ( combining the left side )
x = 180
multiply both sides by 3 then divide both sides by 5
5x = 540 ⇒ x = 108
the 2 angles are x = 108° and x = 72°
Answer:
4.92 hours
Step-by-step explanation:
Let x = the number of hours left to work. I am converting the fraction to a decimal to make it easier to work with.
x + 3 + 5 + 2.08 = 15
Move constants to the right
x = 15 - 3 - 5 - 2.08
Do the math
x= 4.92

Answer: Choice A</h3>
Explanation:
Choice A has the f(x) values going down on the interval -1 < x < 1 only.
Choice B appears to be decreasing over its entire domain, so we can rule this out (since we want -1 < x < 1 to be the only decreasing interval).
Choice C's table isn't decreasing when -1 < x < 1 since y = -3 increases to y = 0 (from x = -1 to x = 0). So we can rule it out.
A similar situation happens with choice D as well, so we can rule this out. The function isn't decreasing when we go from f(-1) to f(0).

B
