Sin30 degrees is 0.50000
With a protractorif it is a computer generated pie chart, find the fraction, and divide into 360
what trapezoid
Find the value of Cos1o.cos2o.cos3o.cos4o......cos179o.Ans: Cos90o=0Therefore, Cos1o.Cos20,Cos30,cos40......Cos900.......Cos1790=0
1/(tangent of angle)
The answer is 1/2.
sin-30 = (-1) x 1/(square root of 2) -sin30 = -(1/square root of 2) They are equal
54 inches Because: sin30=x/9 sin30 is the degrees that makes the apothems angle of depression and 9 is the radius.
cos30
cos60 + sin30 = tan90
sin30 is 1/2 or 0.5
Sin30 degrees is 0.50000
sin30=1/2c0s60=1/2
2*7 = 14 units (the sin of 30° is 0.5 or 1/2 and 7/0.5 = 14) Sin30 = 7/H so H = 7/sin30 = 7/0.5 = 14 (third side is 12.12)
basic algebra, group like terms Sin30-Sin1=Sin(30-2)=Sin(28)
7/sin30 ie 14 units
sin150 is 0.5 Remember that 150o is 5π/6 radians and the reference angle is π/6 or 30o. sin30 is 0.5
