WebAnswer: sine of an angle is always the ratio of the o p p o s i t e s i d e h y p o t e n u s e . s i n e ( a n g l e) = opposite side hypotenuse Example 1 s i n ( ∠ L) = o p p o s i t e h y p o t e n u s e s i n ( ∠ L) = 9 15 Example 2 s i n ( ∠ K) = o p p o s i t e h y p o t e n u s e s i n ( ∠ K) = 12 15 WebIf we consider the right angle, the side opposite is also the hypotenuse. So sin (90)=h/h=1. By pythagorean theorem, we get that sin^2 (90)+cos^2 (90)=1. So, substituting, 1+cos^2 (90)=1 cos^2 (90)=0 cos (90)=0 And we see that tan (90)=sin (90)/cos (90)=1/0. … WebTo find an angle's size, use the sine rule formula where the angles are on the top. Sin (A)/a= Sin (B)/b As mentioned earlier, you only need two parts to use the sine rule, one side, and an opposite angle. Example 1 Work out angle n° in a triangle where one of the angles is 75°, and the two sides are 8 and 10cm. Solution onshore y offshore

Law of Sines If a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of sines states: a sin A = b sin B = c sin C iochow home

"WebThe range of inverse sine is restricted to the first and fourth quadrants. So what this means is using the Law of Sines is only ever going to give you acute angles. If you want to find the obtuse angle, you have to subtract the acute angle from 180 or just use the Law of Sines on the smallest angle to ensure it works. ( 30 votes) Flag Show more...

Using the Sine Function to Find the Angle - Mathematics …

WebThere can be two since sin (theta) = sin (180-theta) for all values of theta that are real numbers e.g. -1000.98, sqrt (2) etc. Since you are using the sin^-1 function you will only ever get 1 angle as the range is defined from -90 to 90 degrees (which is -pi/2 to pi/2 in radians). You can it sketch on desmos to see what it look likes. WebWe then set the expressions equal to each other. bsinα =asinβ ( 1 ab)(bsinα)= (asinβ)( 1 ab) Multiply both sides by 1 ab. sinα a = sinβ b b sin α = a sin β ( 1 a b) ( b sin α) = ( a sin β) ( 1 a b) Multiply both sides by 1 a b. sin α a = sin β b. Similarly, we can compare the other ratios.
