What is the sine of 30 degrees?
sin(30) = 0.5
The shorter leg of a 30-60-90 degree triangle is 6 what is the length of the other leg?
Use the Sine rule. If L is the length of the longer leg, then L/sin(60) = 6/sin(30) So that L = 6*sin(60)/sin(30) = 12*sin(60) = 12*sqrt(3)/2 = 10.39 units.
Sin 30 in trignometry?
=1/2=0.5
What is the cofunction of sin 30 degree?
cos 60
The function y equals sin θ is not a function beacause sin 30 equals sin 150?
Y=sin X is a function because for each value of X, there is exactly one Y value.
What is the answer to sin of 390 degrees?
sin(360+30) =sin(30)= 1/2
Evaluate the expression sine 30 degree cosecant 30 degree?
Sin(30) + cosec(30) = sin(30) + 1/sin(30) = 0.5 + 1/0.5 = 0.5 + 2 = 2.5
What is the sin theta of 30 degrees?
Sin theta of 30 degrees is1/2
What is equivalent to sin 210 degree?
Sin -30
Is this statement true or falseIf sin 30° = 0.5, then sin-1 0.5 = 30°?
true
Find the value of a if tan 3a is equal to sin cos 45 plus sin 30?
If tan 3a is equal to sin cos 45 plus sin 30, then the value of a = 0.4.
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).
How do you determine the leg length of a dodecagon circumscribed within a circle with a known radius?
If you mean "inscribed within", the formula is r/(√2 + √6). To see why this is true, consider a "slice" of the dodecagon - a triangle with corners at two connected corners of the dodecagon and at the center of the circle. Its sides are r, r, and s (the length of a side); the angles are 75, 75, and 30. By the Law of Sines, we have that s = r*sin(30)/sin(75). sin(75)=sin(30+45)=sin(30)cos(45)+cos(30)sin(45). We know the values for sine and cosine of 30 and 45; when we substitute them into the sin(30)/sin(75), we get 1/(√2 + √6). This gives us the formula above.
