Which best explains why the orthocenter of an obtuse triangle is outside the triangle?
Nezavi [6.7K]

Answer: All three of the altitudes lie entirely outside the triangle.

Step-by-step explanation:

The orthocenter is the center of the triangle formed by creating all the altitudes of each side.  

The altitude of a triangle is formed by creating a line from each vertex that is perpendicular to the opposite side.  

In acute traingle , the orthocenter lies inside it.

In right angled triangle, the orthocenter lies on the triangle.

In obtuse triangle , the orthocenter lies outside the triangle because all the three altitudes meet outside .

So, the best explains why the orthocenter of an obtuse triangle is outside the triangle : All three of the altitudes lie entirely outside the triangle.

6x + 3y = 9
anzhelika [568]

Answer:

A

Step-by-step explanation:

Given the 2 equations

6x + 3y = 9 → (1)

2x + 3y = 1 → (2)

Subtracting the 2 equations term by term eliminates the y- term

Subtract (2) from (1) term by term, that is

(6x - 2x) + (3y - 3y) = 9 - 1

4x = 8 ( divide both sides by 4 )

x = 2

Substitute x = 2 into either of the 2 equations and evaluate for y

Substituting into (2)

2(2) + 3y = 1

4 + 3y = 1 ( subtract 4 from both sides )

3y = - 3 ( divide both sides by 3 )

y = - 1

The solution is x = 2, y = - 1 → A

What is the midpoint of a line segment with endpoints at (3,-2) and (1,7)? A. (2,-9/2) B. (2,-5/2) C. (2,5/2) D. (2,9/2)
Ulleksa [173]

The Midpoints of the line segment is (2, 5/2)

Step-by-step explanation:

The line is defined by starting and ending coordinates.

As given in the question starting coordinates are given as (3,-2) and the ending coordinates are provided as (1,7)

The midpoint of the life segment-

The midpoint of the line can be found by individually finding of each “x” and “y” coordinate from both ends.

Thus, x coordinate of the midpoint is (3+1)/2= 2

Similarly, the Y coordinate of the midpoint is (-2+7)/2 = 5/2

Hence the Midpoint of the life segment- (2, 5/2)
