Answer:
C. Centroid
Step-by-step explanation:
The circumcenter is the center of a triangle's circumcircle (circumscribed circle over triangle). It can be found as the intersection of the perpendicular bisectors.
The incenter is the center of the incircle (inscribed circle into a triangle) of a triangle. The incenter can be constructed as the intersection of angle bisectors.
Centroid is the point where the three medians of the triangle intersect.
The intersection of the three altitudes of a triangle is called the orthocenter.
Since three medians intersect at point which divides each median into 2:1 ratio, the answer is centroid.
Factor both equations, you'll get (x-9)(x+1) for the first one and (x+1)(x-1) for the second one.
new equation: (x-9)(x+1) over (x+1)(x-1). You can cancel out both (x+1)s because when divided by each other you're left with the number one. The answer is (x-9) over (x-10
Answer:
the height is 9.8 cm
Step-by-step explanation:
71.54 ÷ 7.3 = 9.8
Answer: First option.
Step-by-step explanation:
You can use the inverse tangent function to find the value of the angle T:
You can identify in the figure that:
Then, knowing these values, you can substitute them into .
Therefore, you get that the value of the angle T rounded to the nearest degree is:
This matches with the first option.
Answer:
131
Step-by-step explanation:
supplementary angles are any two angles whode sum is 180. If v= 49 then 131 would be W. 131+49= 180
