tan(30 deg) = 0.5774, approx.
45 degrees
First make sure your calculator is in 'Degree Mode (D)'. Then using the 'Inverse' of 'Sin' , shown as 'ArcSin' or ' Sin^(-1)' . enter '0.5', followed by '=' . The answer should be '30' ( 30 degrees).
the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.
Cotangent is ' 1/tangent' or ' Cosine / Sine'.
There can be no tangent side. The tangent of an angle, in a right angled triangle, is a ratio of the lengths of two sides.
If the tangent of the angle is [0.171], then the angle is approximately [9.704 degrees] (rounded)
90 degree
30 degree angle
Yes.
a 60 degree angle is twice the size of a 30 degree angle.
The takeoff for a 30 degree angle will depend with the offset angle.
cotangent(50) = 1/tangent(50) = 0.8391
The angle would be 82.4053 degrees, or 82.4 correct to the nearest tenth of a degree.
Yes and they are both acute angles
a 60-degree angle
The tangent secant angle is the angle between the tangent to a circle and the secant, when the latter is extended.
