How to solve law of sines
WebWhen you write and solve the law of sines, you end up with sinC=0.32 or something. You type sin^-1 (0.32) in your calculator and you are given an acute angle. Actually there are two solutions to the equation sinC=0.32. One is acute (your calculator gave it to you) and the other solution is obtuse.

Web10.1 Non-right Triangles: Law of Sines - Algebra and Trigonometry 2e OpenStax β = 180° − 50° − 30° = 100° α = 50° a = 10. c. sin ( 50°) 10 = sin ( 30°) c c sin ( 50°) 10 = sin ( 30°) Multiply both sides by c. c = sin ( 30 °) 10 sin ( 50°) Multiply by the reciprocal to … Web7.2 1 The Law of Sines In this section we will solve triangles that are not necessarily right triangles. Triangles with no right angles are called oblique. Oblique triangles either have three acute angles (less than 90°), or have two acute angles and one obtuse angle (greater than 90°). Acute Triangle Obtuse Triangle We will label the triangles similarly to right …
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) ( … WebThe law of sines establishes the relationship between the sides and angles of an oblique triangle(non-right triangle).
