Answer:46
Step-by-step explanation:Regular polygons are shapes made of straight lines with certain relationships among their lengths. For instance, a square has 4 sides, all the same length. A regular pentagon has 5 sides, all the same length. For these shapes, there are formulas for finding the area. But for irregular polygons, which are made of straight lines of any length, there are no formulas, and you need to be a little creative to find the area. Fortunately, any polygon may be divided into triangles, and there is a simple formula for the area of triangles.
Label the vertices (points) of the polygon starting with 1 at an arbitrary vertex and continuing clockwise around the polygon. There should be as many vertices as there are sides. E.g. for a pentagon (five sides) there will be five vertices.
Draw a line from vertex 1 to vertex 3. This will make one triangle, with vertices 1, 2, and 3. If there are only 4 sides, it will also make a triangle with vertices 1, 3 and 4.If the polygon has more than 4 sides, draw a line from vertex 3 to vertex 5. Continue in this way until you run out of vertices.
Compute the area of each triangle. The formula for the area of a triangle is 1/2 * b * h, where b is the base and h is the height.
Add up the areas, and this is the area of the polygon.
Answer:
5 / 6
Step-by-step explanation:
Given that:
Probability that a dice rolled once will not land on 2
Probability = required outcome / Total possible outcomes
Total possible outcomes = (1, 2, 3, 4, 5, 6)
Required outcome = 2
P(not land on 2) = 1 - p(land on 2)
P(land on 2) = 1/6
P(not land on 2) = 1 - 1/6
P(not land on 2) = 5/6
Answer: x=5.33333333333
Step-by-step explanation:
6=x+2/3
We simplify the equation to the form, which is simple to understand
6=x+2/3
Simplifying:
6=x + 0.666666666667
We move all terms containing x to the left and all other terms to the right.
-1x=0.666666666667-6
We simplify left and right side of the equation.
-1x=-5.33333333333
We divide both sides of the equation by -01 to get x.
x=5.33333333333

I would like for you to be a bit more specific in your question, but, generally, congruent figures have both angles and sides measurements equal to each other. This means that they have to be of the same shape too. So if you know that one side of a figure is 5 units, for example, then the same side of another congruent figure is also going to be 5 units.
