Answer:
Option A. is correct
Step-by-step explanation:
The circumcenter is a point of intersection of all the perpendicular bisectors of a triangle.
The incenter is a point of intersection of all the angle bisectors of a triangle.
The orthocenter is a point of intersection of all the altitudes of a triangle.
The centroid is a point of intersection of all the medians of a triangle.
The incenter, orthocenter, and centroid always lie inside a triangle.
However, a circumcenter does not always lie inside a triangle.
In an acute-angled triangle, the circumcenter may lie inside or outside the triangle.
So,
Option A. is correct
X should equal 100. Hope this helps :)
Answer:
C=29
Step-by-step explanation:
a^2 + b^2 = c^2
21^2 + 20^2 = c^2
441 + 400 = c^2
841 = c^2
\sqrt(841) = \squrt(c^2)
29 = c
The new reflected point across the x-axis of(-3,-3) will become (-3,3)
And the new reflected point across the y-axis of (-4,-4) will become (4,-4)
Answer:
The answer is x < 8
Step-by-step explanation:
12x > 9(2x− 3) − 21
12x > 18x - 27 - 21
12x > 18x -48
12x - 18x > -48
-6x > -48
6x < 48
x < 48/6
x < 8
