A ski slope is 250 yards long with a vertical drop of 100 yardsfind the angle of depression of the slope?
The angle of depression is equal to the angle of elevation, so use the sine ratio to find the angle. sine = opposite (the vertical drop) divided by the hypotenuse (the ski slope) sine = 100/250 = 2/5 or 0.4 sine-1(0.4) = 23.57817848 degrees which is about 24 degrees
What is the trig ratio equal to the opposite side divided by the hypotenuse?
sine
Fill in the blank If the shortest leg of a 30-60-90 triangle has length 11 the length of the hypotenuse is?
22, The shortest side is opposite the smallest angle. As it is a right angle triangle, the Sine ratio can be used: Sine = opposite/hypotenuse ⇒ hypotenuse = opposite/sine = 11/sine 30o = 11 ÷ 1/2 = 22
The sine of a 30 degrees angle equals what?
the sine of a 30 degree angle is 0.5
The sine of a 37 degree angle?
0.602
A sentence using the word sine die?
First of all, a sine is the trigonometric function that is equal to the ratio of the opposite a given angle to the hypotenuse.The teacher told us to use the word sine in a sentence.He told us what a sine is and how you use it.A sine is the trigonometric function that is equal to the ratio of the opposite a given angle to the hypotenuse.
Are angle of incidence and angle of refraction proportional?
No, the angle of incidence and angle of refraction are not directly proportional. They are related through Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities of light in the two mediums.
How do you figure out the sine of a triangle?
An angle can have a sine ratio, not a triangle.
In a right triangle what is the ratio of the opposite side to the adjacent side?
The ratio is called the tangent of the angle. (also equal to sine/cosine)
What ratio do you use to find the sine of an angle in a right triangle?
Sine ratio = opposite/hypotenuse
The tangent of an angle equals the ratio of the?
Sine of the angle to its cosine.
The tanget of an angle equals the ratio of the?
Sine and the cosine of the angle.
How do you compare the angle of incidence and the angle refraction?
The angle of incidence is the angle between the incident ray and the normal to the surface, while the angle of refraction is the angle between the refracted ray and the normal to the surface. These angles are related by Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two media the light is traveling through.
Does the index of refraction equal the angle of refraction?
Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index
What ratio correctly describes the sine function?
In a right triangle, the sine of an (non right angle) angle would the ratio of the opposite side (opposite to the angle selected) and the hypotenuse
What is the ratios function of sin?
The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.
Which ratio is used in finding the sine of an angle in a right triangle?
It is: sine = opposite/hypotenuse
