360°ডিগ্রী থেকে 90°45°30°ডিগ্রি কোণ কিভাবে বের করা যায়?How to find angle from 360° to 90°45°30°degree?
Description:
The Babylonian civilization used a number system based on 60. A clay tablet was found in Babylon (present-day Iraq) in 1950. On that plaque, the circumference of the circle and a balanced hexagon were drawn in between. That regular hexagon can be divided into 6 equilateral triangles. Each angle of an equilateral triangle is 60 degrees. This standard, however, was adopted by the Babylonians as the unit of angle measurement. However, all the central angles of 6 equilateral triangles will be equal to 6×60°= 360°.
If two straight lines lie on top of each other, the angle between them is 0 degrees. And if one line makes a complete turn and rests on the second line, then an angle of 360 degrees is produced.
👉How to find the value of Sin 90?
Answer: The sin value of 90 degrees is 1, equal to the radian sin of 90 degrees. 90 degrees in radians is found by multiplying 90 degrees by π /180 degrees. Trigonometric functions are usually defined as the ratio of two sides of a right triangle containing an angle less than a right angle.
👉How to find the value of 45°? Answer: While finding the value of 45° we will first see which finger is 45°. The value of the third finger we take to be 45°, the number of fingers below it is 2; So if we divide by two with the square root of 2 we get the value of sine 45°. 👉How to get 30° value? Answer: First we will look at a circle and then find the value of 60° and create any arc with any size divider in the middle. Then I will create another curve from the first point of the same measurement.Then we add the first arc we drew to the midpoint of the arc and we get the 30° value.
