Sin(10)*12 = 12*sin(10) = 12*0.1736 = 2.0838, approx.
A 12/12 is 45 degrees. If you set a 45 degree piece of wood on the roof it should be level.
In angle measurement, 60 minutes = 1° 57° 12' = 57.2 ° Sin 57.2 = 0.84057 (5dp)
A roof angle of 6 degrees = 1.26 / 12 rise or pitch.
A 10/12 means for every foot of run your rise is 10". so, 10' x 10" = 100" rise in 10 feet.
Trigonometry includes 12 baisic functions. Sine, Cosine, and Tangent are the three most baisic. Each of those functions has a reciprocal. Cosine's reciprocal is Secant, Sine reciprocal is Cosecant, and Tangent's reciprocal is Cotangent. Each of those six functions has an inverse funcion called Inverse Sine, Cos etc... or Arcsine, Arcosine, Arcsecant, etc.... The shorthand for each function is sin, caos, tan, sec, csc, cot. The inverses have a -1 notation like sin-1.
Rearrange the sine ratio of sine = opposite/hypotenuse: hypotenuse = opposite/sine hypotenuse = 12/sine 30 degrees = 24 Therefore the hypotenuse is 24 units in length.
It is approx 0.2170
The value of sine and cosine varies between -1 and 1, it never can be 12. If you mean .12, then we have: sin x = .12 x = sin-1 .12 x = 6.89 degrees So that, cos x = cos 6.89 = .99

-12 degrees Fahrenheit = -24.4 degrees Celsius.
It is cool. 12 degrees Celsius equals 53.6 degrees Fahrenheit.
Using the cosine formula the angle between lengths 8 and 12 is 55.77113367 degrees. Using the sine formula the area of the triangle is 39.68626966 or about 40 square units.
80 degrees longitudinal is equals to 8070 degrees longitudinal is equals to 70
12 + 10 + 11 equals 33
-12 degrees C is lower than -10 degrees C
For you A+ Cheaters ;D it's 50!
