Which best explains why the orthocenter of an obtuse triangle is outside the triangle?

a. all three of the altitudes lie entirely outside the triangle.
b. two of the altitudes lie entirely outside the triangle.
c. all three of the medians lie entirely outside the triangle.
d. two of the medians lie entirely outside the triangle.

A is the right answer.All three of the altitudes lie entirely outside the triangle.

Step-by-step explanation:

Orthocenter of a triangle is a point which formed by intersection of all the three concurrent altitudes. It can be inside or outside of a triangle. In obtuse triangle All three of the concurrent altitudes lie entirely outside the triangle .Therefore its intersection will lie outside and that intersection is orthocenter of the obtuse triangle .

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
