What is the reference angle of 331?
Since the angle of 331⁰ is in the fourth quadrant, then the measure of its reference angle in the first quadrant is 360⁰ - 331⁰ = 29⁰ .
Is snell's law true when angle of incidence is angle 0 degree?
Yes; if angle of incidence is zero angle of refraction is zero regardless of index: sin theta r = (n1/n2) sin theta i
What is the reference angle for a angle that's 497 degrees?

What is the difference between sin x and sin -1 x .?
-- sin(x) is a number. It's the sine of the angle 'x'. -- sin-1(x) is an angle. It's the angle whose sine is the number 'x'.
What is the reference angle for 243 degree?
The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. For an angle of 243 degrees, which is in the third quadrant, the reference angle can be found by subtracting 180 degrees from it. Thus, the reference angle is 243° - 180° = 63°.
What is the name of a 285 degree angle?
Angle greater than 180 degrees are reflex angles.
What is the reference angle for an angle with the measure of 175 degrees?
The reference angle for an angle with the measure of 175 degrees is 5 degrees
What is the reference angle of negative 200 degrees?
To find the reference angle for negative 200 degrees, first convert it to a positive angle by adding 360 degrees, resulting in 160 degrees. The reference angle is then found by subtracting this angle from 180 degrees, yielding a reference angle of 20 degrees. Thus, the reference angle for negative 200 degrees is 20 degrees.
What is the answer for mathematics 4 page 285?
sin z = 7/25 = 0.28
What is the reference angle of 210 degrees?
The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. For an angle of 210 degrees, which is in the third quadrant, the reference angle can be found by subtracting 180 degrees from it: 210° - 180° = 30°. Therefore, the reference angle for 210 degrees is 30 degrees.
What is the reference angle for an angle with a measure of 175 degrees?
The reference angle is the acute angle formed by the terminal side of the given angle and the x-axis. For an angle of 175 degrees, which is in the second quadrant, the reference angle can be found by subtracting it from 180 degrees: 180° - 175° = 5°. Therefore, the reference angle for 175 degrees is 5 degrees.
If an arc subtend angle of 75 what is angle subtended by it on remaining part of circle?
360 - 75 = 285
What is the reference angle of 10 degrees?
The reference angle is the acute angle formed between the terminal side of the angle and the x-axis. For an angle of 10 degrees, since it is already in the first quadrant and is acute, the reference angle is simply 10 degrees itself. Thus, the reference angle for 10 degrees is 10 degrees.
What is the sin of a 37 degree angle?
sin(37) = 0.6018150232
What is the perimeter of a triangle when an angle of 57 degrees is opposite to a side of 14.5 inches and has another angle of 71 degrees?
The sum of tthe angles of a triangle is 180° which means the third angle is 180° - (57° + 71°) = 52° The sine rule gives: a/sin A = b/sin B = c / sin C where side a is opposites angle A, etc. The sine rule can be used to find the lengths of the other two sides when the angles are all known and one side length is known. Let angle A = 57°, then side a = 14.5 in. Let angle B = 71° and angle C = 52° Using the sine rule: a/sin A = b/ sin B → b = a × sin B/sin A Similarly, c = a × sin C/sin A → The perimeter = a + b + c = a + a × sin B/sin A + a × sin C/sin A = a(1 + sin B/sin A + sin C/sin A) = 14.5 in × (1 + sin 71° / sin 57° + sin 52° / sin 57°) ≈ 44.47 in ≈ 44.5 in
