The term that best describes the point L is (d) the centroid
<h3>How to determine the point L?</h3>
From the figure, we can see that:
The three lines drawn from point L divide the sides of the triangles into equal segments.
Also, the lines from point L are perpendicular to the sides.
The above description represents the definition of a centroid
Hence, the term that best describes the point L is (d) the centroid

Answer:
The average speed is 7.5
Step-by-step explanation:
Speed is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it.
Then, the average speed relates the change in position to the time taken to effect that change:
The change in position is the difference between the final position and the initial position, while the change in time is the difference between the final and initial time.
In this case, the starting and ending positions are calculated by replacing the times in the function of the distance d (t):
d(5)= 0.5*5²= 12.5 m
d(10)= 0.5*10²= 50 m
So:
- change in position= final position - initial position= 50 m - 12.5 m= 37.5 m
- change in time= 10 s - 5 s= 5 s
Replacing in the definition of speed:
and solving you get:
speed= 7.5
<u><em>The average speed is 7.5 </em></u><u><em></em></u>

Answer:
The Exterior Angle of a Triangle Formula states that the measure of an exterior angle is equal to the sum of its remote interior angles. Therefore, r + 58 = 130 which means r = 72°.
