Ответ:
D
Step-by-step explanation:
An Angle bisector of a triangle divides the angles of the triangle into two parts that are porportional.
I hope you found this useful
Ответ:
D.Angle bisector
Step-by-step explanation:
Angle bisector because it cuts the angle D in half and when it bisects segment EF it doesnt create a right angle. So the line turns point X into a midpoint
I hope this helps.

Part a) The equation in point slope form is![y-11.2=-0.025(x-37)](/tpl/images/0356/6234/1e6aa.png)
Part b)![6.1\ in](/tpl/images/0356/6234/c8d56.png)
Step-by-step explanation:
Part a) Determine the equation of the line in point slope form
Let
x -----> the time in minutes
y -----> the height of the candle in inches
we know that
After 37 minutes, the candle was 11.2 inches tall
so
we have the point
(37,11.2)
Eighteen minutes later, it was 10.75 inches tall
so
we have the point
(37+18,10.75) -----> (55,10.75)
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to
substitute the values
The equation of the line in point slope form is equal to
we have
substitute
Part b) Determine the height of the candle after 4 hours
Remember that
so
For x=240 min
substitute in the linear equation
