Sep 02, 2010 · Use the law of sines to find the possible measures of B. Law of sines sin B = = _0.75_ Evaluate. There are two angles B between 0° and 180° for which sin B = _0.75_. One is acute and the other is obtuse. Use your calculator to find the acute angle: sin(1 0.75 ( _48.6°_. The obtuse angle has _48.6°_ as a reference angle, so its measure

A) Use of calculator. sin = sin x = .4741. B) Create right triangles. 1) If A = and b = 25, find a. 2) If A = , a = 1. find b and c. 3) C) Angle of elevation is the angle between the horizontal and the line of sight to the top of an object. Angle of depression is determined by the horizontal line down to the line of sight.

Using your calculator look at the graph of the functions f(x)=sin x and f(x)=sin(4x). Notice the graph repeats 4 times in the length of time it took sin x to complete one period. So the period of f(x)=sin(4x) is or . Look back at 9c. The 2 shifted the graph 2 units to the left.

If we use the Law of Sines (short side first), we obtain 3/sin (26.4°) = 4/sinB or B=36.4 and C=180°-36.4°-26.4° ≈ 117.2 ° When using the Law of Cosines use the longest side first to detect any obtuse angle, and then use the Law of Sines freely.
