Because almost 97 percent of the people living in poland are of polish ethnic descent, poland is a(n) society. a. genetically diverse b. ethnically homogeneous c. genetically endangered d. ethnically heterogeneous

Right ethnically homogeneous

Polish society is ethnically the most homogenous in Europe, and has the lowest birth rate in this continent.

Therefore, the majority of the population is Polish and the correct option is B.

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.
