What rise does a 30 degree angle give over 5 m?
5*sin(30) = 2.5 metres.
The lentgh of the hypotenuse of a 30 -60 degree right triangle is 7.5 meters find the length of the opposite side of the 30 degree angle?
It is: 7.5*sin(30) = 3.75 meters
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.
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
Sin A equals 0.3779 find the degree and how?
22.20366435 sin^-1(0.3779)
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 equivalent to sin 210 degree?
Sin -30
What is Sine in a 30-degree-angle?
sin(30) = 1/2
A 30-60-90 triangle has a hypotenuse of length 44. What is the length of the side opposite the 30 degree angle?
I assume your 90 degree angle is on the right and the 30 degree angle is opposite that. ( degree mode ) sin theta = opposite/hypotenuse sin 30 degrees = opp./44 = 22
What is the sin of a 30 degree angle?
sin30 is 1/2 or 0.5
How do you solve the following identity sec x - cos x equals sin x tan x?
sec x - cos x = (sin x)(tan x) 1/cos x - cos x = Cofunction Identity, sec x = 1/cos x. (1-cos^2 x)/cos x = Subtract the fractions. (sin^2 x)/cos x = Pythagorean Identity, 1-cos^2 x = sin^2 x. sin x (sin x)/(cos x) = Factor out sin x. (sin x)(tan x) = (sin x)(tan x) Cofunction Identity, (sin x)/(cos x) = tan x.

If the side opposite a 30 degree angle in a right trangle is 12.5 meters how long is the hypotenus?
12.5/sin(30) = 25 meters
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
What is the answer to sin of 390 degrees?
sin(360+30) =sin(30)= 1/2
