What is the exact value or sin 22.5?
The exact value of sin 22.5 is 0.382683432
What is the value of x in a 90 degree triangle with a hypotenuse of 30 and a 45 degree angle x is the opposite of the 45 degree angle us a trigonometric function?
Use and rearrange the sine ratio: 30*sin(45) = 21.21320344 units
If angle A is 60 degrees angle B is 45 degrees angle C is 75 degrees and the length of side AC is 10 units then what is the length of side AB?
This problem can be solved using the Sine Rule :a/sin A = b/sin B = c/sin C 10/sin 45 = AB/sin 75 : AB = 10sin 75 ÷ sin 45 = 13.66 units (2dp)
What is the absolute value of -45?
The absolute value of any negative integer is equal to its value without the minus sign. In this instance, abs(-45) = 45.
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.
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.
Find out value of sin 45 cos 45 - sin 230?
Assuming that the angles are all stated in degrees: sin(45) = cos(45) = 1/2 sqrt(2) sin(45) cos(45) = (1/2)2 x (2) = 1/2 sin(230) = - 0.7660444 sin(45) cos(45) - sin(230) = 0.5 + 0.7660444 = 1.2660444 (rounded)
How will the value of sin 35 determine?
to find sin 35 here we take the angle = x=15 then 3x=45 , 4x=60 then 4x-3x=60-45 then by putting sin on rhs we will get cos 35 and sin 35 hope it helped you
Find the value of 3 sin 40 4 cos 20 - tan 45?
6.25
What is exact value of sin75?
sin(75) = sin(45 + 30) = sin(45)*cos(30) + cos(45)*sin(30) = [1/sqrt(2)]*[sqrt(3)/2] + [1/sqrt(2)]*[1/2] = 1/[2*sqrt(2)]*[sqrt(3) + 1] that is [sqrt(3) + 1] / [2*sqrt(2)]
What if the sine of an angle is 0.707 what is value of that angle in degrees?
sin-1(0.707) = 44.99134834 or about 45 degrees
Cos 45 degrees equals sin?
cos(45) = sin(45) You can see this as follows: imagine a circle with radius 1. The point on the circle with angle 45 degrees, lies on the line y=x, equally far from the x-axis (cos) as the y-axis (sin). The angle for both must be 45, because x and y are orthogonal: 90 deg, so if the angle with x is 45, then the angle with y must be 90-45=45. So: for this point, both angles are 45, and the distance to x (cos) is equal to the distance to y (sin). Therefore, cos(45) = sin(45). Additionally, cos(45) = sin(45+90) = sin(45+360n) = sin(135+360n) with n integer.
A 45-45-90 triangle has the hypotenuse of 1. what is the length of one of its legs?
sin theta = opp/hyp sin 45 = opp/1 opp = sin 45 = sqrt(2)/2 ~= 0.7071
Does tan 45 degrees and sin 45 degrees equal trig values?
They are both trig values, but not equal. Tan 45 is 1 and sin 45 is 0.7071
Fill in the blank Cos equals Sin 45?
45
