Example of different kids of angles?
Acute angles (less than 90 degrees) Obtuse angles (greater than 90 degrees) Right angles ( equal to 90 degrees)
How do you find sin of angle?
The sine of an angle is obtained from a right angle triangle. The other two angles are acute, or less than 90 degrees. The sin of the angle is the side opposite the angle divided by the hypotenuse.
What is the third angle of a right triangle if one of the angles measures Y?
If Y is the right angle then the third angle is indeterminate. Otherwise it is 90 - Y degrees.
What is the difference between the acute obtuse and reflex angles?
Acute angles are greater than 0 but less than 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees but less than 360 degrees
What is the complementary angle of 113 degree angle?
Two angles are complementary if they both add up to 90 degrees. This means that a complementary angle would have to be negative 23 degrees if the given angle is 113 (-23+113=90) . However I suspect that you are looking for the supplementary angle. Supplementary angles total 180 degrees. If so, the supplement would be 77 degrees.
