If ∠B = 21°, ∠c = 46 and side AB = 9 cm in a triangle then solve the triangle. Solution: Given: Two angles and a side. No, let’s use law of sine to solve the triangle. As we know sum of the interior sides of a triangle is 180° Accordingly, ∠A = 113° As AB = c= 9cm. Using the law of sine rule:

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) ( 1 a b) Multiply both sides by 1 a b. sin α a = sin β b. Similarly, we can compare the other ratios. city centre edinburgh postcodeWebThe Law of Sines can be used to solve oblique triangles, which are non-right triangles.
