Because if you construct a right triangle in which the acute angles are 30° and 60°,
you'll find that the side adjacent to the 60° angle is 1/2 the length of the hypotenuse,
which is how you apply the definition of the cosine.

What is cos 60 degrees?
cos(60) = -0.95241298
What is the cos 60 degrees?
I can answer if you tell me what cos means.
What is the cosin of 60?
Cos(60) = -0.95241 assuming that angles are measured in radians, as would be done by most mathematicians. If they are measured in degrees, the answer is 0.5
What is 7 x 60 x cos 60 equals?
cos(60) = 0.57 x 60 x cos(60) = 7 x 30 = 210
What is the value of cos 22.5 degrees?
Cos(22.5)=0.9238795325
What is cos 60 degrees?
cos(60) = -0.95241298
What is the cos 60 degrees?

How do you get angle size of a 60 feet multiply 90 feet?

Why is sine 30 the same as cosine of 60?
sin(30) = sin(90 - 60) = sin(90)*cos(60) - cos(90)*sin(60) = 1*cos(60) - 0*sin(60) = cos(60).
What is 7 x 60 x cos 60 equals?
cos(60) = 0.57 x 60 x cos(60) = 7 x 30 = 210
What is cos 60?
hi,the value of cos 60 is 1/2
How do you find cos 60?
cos(60) = 0.5 The simplest way is to use a calculator.
What is equal to cos 47 degrees?
Cos 43
What is cos zero degrees?
It is: cos(0) = 1
What is the exact value answers in degrees of two cos x minus radical three equals zero?
30 degrees explanation 2Cosx-radical 3=0 Then 2cosx=radical 3 and cos x=(radical 3)/2 Now remember that cos 300 is (radical 3)/2 from the 30/60/90 triangle. So the answer is 30 degrees.
Determine the measure of angle A if 0 degrees is smaller than or equal to A which is smaller than or equal to 90 degrees and cos125 degrees equals negative cos A?
cos(125) = cos(180 - 55) = cos(180)*cos(55) + sin(180)*sin(55) = -cos(55) since cos(180) = -1, and sin(180) = 0 So A = 55 degrees.
