Plug in the 1/2 where the a’s are answer is -3
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.
Answer:

Step-by-step explanation:
Given
Base:




Required
Determine the volume (in litres)
First, we need to calculate the area;
Base on the parameters given, we have:









So:


Quotient means the answer to a division problem. 8 less than the quotient indicates that we have to subtract 8 AFTER we do the division... so your expression would be
(x ÷ 3) - 8 or
x/3 - 8
Answer B
Add the ratio numbers to be your denominator
5+3+7+1=16
Pieces:
5/16 x124=38.75
3/16 x124=23.25
7/16 x124=54.25
1/16 x124=7.75
