Weban obtuse angle; 127°. a right angle; 90°. How to measure an angle with a protractor: Place the midpoint of the protractor on the VERTEX of the angle. Line up one side of the angle with the zero line of the protractor (where you see the number 0). Read the degrees where the other side crosses the number scale. WebMar 3, 2024 · Both will show that x = 30 degrees. 4. Use the cosine function if you know the length of the adjacent side and the hypotenuse. For this type of problem, use the equation: cosine (x) = adjacent ÷ hypotenuse. ... An angle measuring more than 90 but less than 180 degrees is an obtuse angle. An angle measuring 180 degrees is a straight angle ...
