To find the angle in degrees, you can use a protractor to measure the angle directly, or you can use the trigonometric functions (sine, cosine, tangent) to calculate the angle using the lengths of the sides of the triangle.
The formula for finding the angle in degrees depends on the information given. If you have the lengths of two sides of a right triangle, you can use the inverse trigonometric functions to calculate the angle. If you have all three sides of a triangle, you can use the law of cosines to find the angle.
Yes, you can find the angle in degrees without a protractor by using trigonometric functions or the law of cosines. These methods involve using the lengths of the sides of the triangle and do not require a protractor.
The accuracy of the measurements when finding the angle in degrees depends on the precision of the tools used and the skill of the person measuring. Using a protractor may result in more accurate measurements compared to using trigonometric functions, which may introduce rounding errors.
Finding angles in degrees is commonly used in fields such as mathematics, engineering, and physics. It is also used in everyday situations, such as measuring angles for construction, navigation, and sports.
