The sum of the angles inside a triangle is equal to 180°. We are told that angle a is 57°, and that angle b is 73°. This tells us that angle c is is (180 - 57 - 73)°, or 50°. We are also given the length of side ab, 25cm. With that, we can use the sine rule to calculate the length of side ac: sin(b) / |ac| = sin(c) / |ab| ∴ sin(73°) / |ac| = sin(50°) / 24cm ∴ |ac| = 24cm · sin(73°) / sin(50°) ∴ |ac| ≈ 29.96cm

Yes for a given medium critical angle is fixed as mu = 1/ sin C mu is the refractive index of the material and C is the critical angle.

type the value of sine in the calculator and press 2ND SIN for sin-1, or press 2ND SIN for sin-1 and type the value of sine, because -sin(.xxxx) = angle known as inverse sine

The sides and angles of a triangle are generally described using a,b,c for the three sides and A for the angle opposite side a, B for the angle opposite side b and C for the angle opposite side c. Then use the Sine Rule provided that one of the given angles is opposite the given side. a/Sin A = b/Sin B = c/Sin C

First find 180 minus the vertex angle and divide that by 2 to get the other angles. Then solve the other sides by using sin(vertex angle)/base=sin(other angles)/other sides.

The critical angle is given by the formula: Thetac = sin-1(n2/n1) Assuming a diamond-air boundary, this gives the critical angle as: Thetac = sin-1(1.00/2.42) = 24.4 degrees.

Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.

That depends whether 312 is in degrees or in radians. Just open your scientific calculator (there is one included on most computers; don't forget to set it to "scientific"), select the correct angular measurement (usually degrees or radians), and do the calculation.-----If you don't have a scientific calculator you can use google: just enter sin 312 radians or sin 312 degrees.For more general expressions use the link attached below. For example, you can enter sin(312)+cos(312). This site will assume degrees in this instance but offer you the option of calculating the result for radians.

Refractive index of a medium = speed of light in air / speed of light in medium If a ray of light passes from air into that medium then the refractive index (R.I) can be given by: R.I = sin(angle in air) / sin(angle in medium) Angle in air is the angle between the ray of light and the normal in air.

The resultant (sum) of nonconcurrent forces is given by the Law of Cosines, which is the product of the vector sums and their conjugate: C^2 = (A + B)(A + B)*=(AA* + BB* + AB* + A*B)= (AA* + BB* + 2ABcos(AB)) The angle of C is given by sin (C) =A/C sin(AB) angle(C ) is smaller than the angle between A and B, angle(AB).

The sine of an angle is obtained from a right angle triangle. The other two angles are acute, or less than 90 degrees. The sin of the angle is the side opposite the angle divided by the hypotenuse.

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
