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... 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.
