What is Sine in a 30-degree-angle?
sin(30) = 1/2
What is the sin of a 37 degree angle?
sin(37) = 0.6018150232
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's the takeoff for a 30 degree angle?
The takeoff for a 30 degree angle will depend with the offset angle.
How do you find the maximum range and height for angles 30 45 and 60?
1. You need to know the velocity of the projectile (V0) 2. The expressions for the range and height assume no air resistance (in vacuum) 3. The units must be consistent e.g. metres and g = 9.81 m/s2 Range in metres for 30 degree launch angle = sin 60 x V02 / 9.81 Range in metres for 45 degree launch angle = sin 90 x V02 / 9.81 Range in metres for 60 degree launch angle = sin 120 x V02 / 9.81 Max. height in metres for 30 degree launch angle = (V0 x sin 30)2 / 2g Max. height in metres for 45 degree launch angle = (V0 x sin 45)2 / 2g Max. height in metres for 60 degree launch angle = (V0 x sin 60)2 / 2g 2g is of course 9.81 x 2 = 19.62 m/s2 For interest, at 45 degree launch angle the max. height is 25% of the range.
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
The refractive index of water is 1.33 a ray is incident from water on air at an angle of incidence equal to 30 degree what is the angle of refraction in air?
The angle of refraction can be calculated using Snell's Law: n1sin(theta1) = n2sin(theta2), where n1 and n2 are the refractive indices of the media, and theta1 and theta2 are the angles of incidence and refraction, respectively. Given n1 = 1.33, n2 = 1 (since in air), and theta1 = 30 degrees, we can solve for theta2 to find it is approximately 22.62 degrees.
What rise does a 30 degree angle give over 5 m?
5*sin(30) = 2.5 metres.
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
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
Show you a 30 degree angle?
30 degree angle
What is the sin of a 37 degree angle?
sin(37) = 0.6018150232
Is a 30 degree angle congruent to a 30 degree angle?
Yes.
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
How is a 30 degree angle related to a 60 degree anlge?
a 60 degree angle is twice the size of a 30 degree angle.
What is the sin of a 33 degree angle?
0.766
