Suppose a triangle has 3 sides, 3, 4, 6 which of the following must be true
a. the triangle in question is a right triangle
b. the triangle in question is not a right triangle
c the triangle in question may or may not be a right triangle

  B. the triangle in question is not a right triangle

Step-by-step explanation:

A 3-4-5 triangle is a right triangle, so this one, with its longer longest side, is an obtuse triangle. It is not a right triangle.

___

3, 4, 5 is one of the first Pythagorean triples that you learn:

  3² + 4² = 5²

These are the side lengths of the smallest right triangle with integer sides. It is worthwhile to remember. This triple is used not only in many math problems (such as this one), but also in real life when it is useful to lay out a right angle.

12.5 feet

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
