Answer:
14. 53.1°
16. 253.7°
Step-by-step explanation:
14. The measure of angle L can be found from the cosine relation:
Cos = Adjacent/Hypotenuse
cos(L) = 9/15 = 3/5
L = arccos(3/5) = 53.1° . . . arc MK
__
16. Arc MK is half of arc JK, so that arc is 106.3°. The long arc JPK is the difference between 360° and the measure of the short arc JK.
360° -106.3° = 253.7° . . . arc JPK
Answer:
The coordinates of the centroid are:
The diagram is also attached below.
Step-by-step explanation:
Given the vertices
We know that the intersection of medians brings the centroid of the triangle.
The centroid of a triangle is given by
In this example,
substituting in the formula
Therefore, the coordinates of the centroid are:
The diagram is also attached below.
Answer: (x-9)(x+1), so x=9 and x=-1
Step-by-step explanation:
X^2-8x-9=0
-9 times 1 = -9 and -9 plus 1 = -8
So (x-9)(x+1)
X=9, x=-1
