1.00 * sine (45 degrees) = 1.33 * sine (Θr) 0.7071 = 1.33 * sine (Θr) 0.532 = sine (Θr) sine-1 (0.532) = sine-1 ( sine Θr) 32.1 degrees = Θr . Proper algebra yields to the answer of 32.1 degrees for the angle of refraction. The diagram showing the refracted ray can be viewed by clicking the View Diagram button below.

Law of Sines 9. A surveyor measures the angle to the top of a hill from two different points in a valley. The angles she measures and the distance between the valley points are shown in the diagram at the right. What is the distance from point B to the top of the hill? Round your answer to the nearest hundredth of a mile. 10.
Ivan began to prove the law of sines using the diagram and equations below. sin (A) = h/b, so b sin (A) = h. sin (B) = h/a, so a sin (B) = h. Therefore, b sin (A) = a sin (B).

Jun 02, 2020 · First of all this is NOT the law of sines, but the 'Sine Rule , which is a/SSinA = b/SinB'. Substituting 6/SinA = 7/Sin30 Algebraically rearrange SinA = 6Sin30 / 7 Remember Sin30 = 1/2 ; substitute. SinA = 6(1/2) / 7 SinA = 3/7 Then answer is 'A'
