What is the cosine of a 60 degree angle?
Cosine is 0.5
What is the ratio of the cosine of an angle?
Fora right angle triangle: cosine angle = adjacent/hypotenuse
How do you find an angle using sine cosine tangent?
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.
What is the tangent of 30 degree angle?
tan(30 deg) = 0.5774, approx.
What ratio correctly describes the cosine function?
The cosine of theta is adjacent over hypotenuse, given a right triangle, theta not being the 90 degree angle, adjacent not being the hypotenuse, and theta being the angle between adjacent and hypotenuse. In a unit triangle, i.e. in a unit circle circumscribed with radius one, and theta and the center of the circle at the origin, cosine of theta is X.
What is the cosine of a 60 degree angle?
Cosine is 0.5
What is the cosine of a 59 degree angle?
cosine(59 degrees) = 0.51504 (rounded)
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
At what angle measure are the sin and the cosine equal?
45 degree
What is the cosine of a 50 degree angle?
cos(50) = 0.6428 (rounded)
What is the length of the side opposite the 30 degree angle?
It depends on the length of the other two sides which creates that angle. Not enough information was given. However, you can simply use the Cosine rule to find it if the other two lengths are known. a2=b2+c2- 2bccosA (A=30 and a is the length of the side opposite to 30 degree angle; b and c is the length of the sides which makes up the 30 degree angle)
Show you a 30 degree angle?
30 degree angle
What is the cosine of a 65 degree angle?
Cos(65 deg) = 0.4226 approx.
Is a 30 degree angle congruent to a 30 degree angle?
Yes.
How is a 30 degree angle related to a 60 degree anlge?
a 60 degree angle is twice the size of a 30 degree angle.
What's the takeoff for a 30 degree angle?
The takeoff for a 30 degree angle will depend with the offset angle.
How do you find the sec of a 38 degree angle?
Find the cosine of 38 degrees and then find its reciprocal.
