an acute angle, if you're trying to answer a math homework question that's trying to be smart.
Angle of elevation is looking upwards to an object and angle of depression is looking downwards to an object
I suppose you are looking for the name. The common name for a 90o angle is 'right angle'.
The angle of depression is looking at an object below your line of sight.
Obtuse angle if your looking for the word.
For trigonometry if you have the value of the hypotenuse and the angle, it depends what side you are trying to find. If you are looking for the side across from the angle, the formula is sine(angle)=opposite side divided by hypotenuse. If you are looking for the side adjacent to the angle, the formula is cosine(angle)=adjacent side divided by hypotenuse. Hope this helps!
The angle of elevation is looking at an object above your line of sight.
by looking to at it by looking to at it
So basically , you have an right angle and another angle . You draw an right angle over the angle your looking at and if its smaller than the right angle then its an acute angle . If its bigger than the right angle then its a obtuse angle . GoodLuck!(;
While looking for computer stands, it is important to try them out. Pay attention to the angle that your arms form when you try them. You are looking for a horizontal angle to the stand.
If you are looking for an angle in radians, then pi radians equals 180 degrees.
If it is a complementary angle, the missing angle is 52 degrees. If it is a supplementary angle, the missing angle is 142 degrees. If it is an opposite angle, the missing angle is 38 degrees. Obviously, you need to know what type of angle you're looking for.
