Answer:
Circle graphs
A circle is the same as 360°. You can divide a circle into smaller portions. A part of a circle is called an arc and an arc is named according to its angle.
A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.
The vertex angle bisector divides the triangle into two congruent right triangles. The sine of half of the vertex angle will be half of the base divided by the side (from the definition of the sine of an angle). Then the total vertex angle is ...
α = 2×arcsin(3.5/5) ≈ 88.9°
_____
Using the Law of Cosines, the vertex angle can be found as
arccos((7^2 -5^2 -5^2)/(-2*5*5)) = arccos(1/50) ≈ 88.9°
Answer:
Step-by-step explanation:
The volume of a cube is 200 cm².
We need to find the edge length of the cube.
The formula for the volume of a cube is given by :
a is the side of the cube
![a=\sqrt[3]{200} \\\\=(200)^{\dfrac{1}{3}}\\\\=(25\times 8)^{\dfrac{1}{3}}\\\\=(25)^{\dfrac{1}{3}}\times (8)^{\dfrac{1}{3}}\\\\=2(25)^{\dfrac{1}{3}}](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B3%5D%7B200%7D%20%5C%5C%5C%5C%3D%28200%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D%2825%5Ctimes%208%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D%2825%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5Ctimes%20%288%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D2%2825%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D)
So, the edge length of the cube is .
1x x 1x x1x is the answer
