take the number and divide it by 180 if it's a triangle
999999
there is no fix formula for this..........you have to check that what is given to you in the question. According to the given you have to find the interior angle.
216 is the angel of g
40 sides
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
1 plus 2 is equal to 3

there is no fix formula for this..........you have to check that what is given to you in the question. According to the given you have to find the interior angle.
Measure the two sides adjacent to the angle and the diagonal at the far ends of these sides. Then use the cosine rule to calculate the angle.
216 is the angel of g
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
40 sides
135 degree
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
The lengths of all three sides of the triangle APEX:)
use your ruler to measure the sides
use a protractor.
