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.
If you know the angle's sine, cosine, or tangent, enter it into the calculator and press <inverse> sine, cosine, or tangent. On MS Calc, in Scientific Mode, using Degrees, enter 0.5, then check Inv and the press sin. You should get 30 degrees. The other functions work similarly.
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.
1/(tangent of angle)
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
The tangent secant angle is the angle between the tangent to a circle and the secant, when the latter is extended.
