Pyramid is a 3 dimensional object. Polygon is a 2 dimensional object. You will still need something to make it a 3 dimensional object. Look at the picture below which is a polygonal pyramid.

whihc question is not a good survey question? dont you agree that the financial crisis is essentially over? on average how many
Neko [114]

Answer:

The correct answer would be option A, Don't you agree that the financial crisis is essentially over.

Step-by-step explanation:

A survey questionnaire is a series of question which is set formally to be asked from a specific sample of a population to gather, analyze and interpret the data obtained from the sample population. So the questions in the survey must be structured, to the point, clear, short and straight. Survey questions are desirably closed ones and the ones which do not need much explanation by the person who is doing the survey. So the first question in this question require an explanation, and also the question is not structured, clear and to the point and thus is not a good survey question. Comparatively, the second question is more structured, clear and to the point and such questions are normally desirable in the surveys.

What is the answer lol somebody help me please and thank you !
PilotLPTM [1.2K]

I'm guessing that you know about 45-45-90 and 30-60-90 triangles.

In 45-45-90 triangles, the legs are in a ratio such that the hypotenuse is \sqrt{2} times the legs.

In 30-60-90 triangles, the legs are in a ratio of 1:\sqrt{3}:2

In the picture given we have been given a value of the side of the 45-45-90 triangle. We can deduce that the value of the hypotenuse is 9\sqrt{2} because of the ratio of the sides of a 45-45-90 triangle.

The 30-60-90 triangle shares the same hypotenuse, and so we now know a value of one of its sides as well. The ratio of the side of value 'x' and the hypotenuse is \sqrt{3} : 2

We can create an equation to solve for x using these ratios:

\frac{\sqrt{3} }{2} = \frac{x}{9\sqrt{2} }

Cross multiply:

2x = 9\sqrt{6}

x = \frac{9\sqrt{6} }{2}
