D. a piece of a line that starts at the endpoint and extends indefinitely in one direction
think of an arrow with a dagger on one end! :)
An angle bisector is one that cuts an angle into two equal halves.
bearing in mind that a degree has 60 minutes and a minute has 60 seconds, so then 171°30' is just 171 degrees and 30 minutes.
let's halve each, 171 ÷ 2 = 85.5°, so 85.5° is really 85° and half of another degree, let's recall that a degree has 60 minutes, so half of a degree is just half of 60 minutes, namely 30 minutes, so 85.5° is really 85°30'.
let's halve the 30 minutes now, half of 30 is 15, so 15 minutes is its half.
now let's add both halves together, 85°30' plus 15', 85°45'.
Answer:
B. 2x^2 − x
Step-by-step explanation:
3x^2 + x − x^2 − 2x
We need to combine like terms
3x^2 -x^2+ x − 2x
2x^2 -x

Answer:
4 1/2 days
Step-by-step explanation:
The time is given by ...
time = quantity/rate
time = (3/4 fence)/(1/6 fence/day) = (3/4)(6) days = 4 1/2 days
