WebSimilarly, the cosine of an angle is the ratio of the adjacent side to the hypotenuse. If we pause and imagine a right triangle, the sine of one angle would be the cosine of the angle across from it, since the hypotenuse is constant, but the opposite side of one angle and the adjacent side of the other angle refer to the same side. WebAs the sum of angles in a triangle is 180 0 Accordingly, angle A = 113 0 As AB = c = 9 cm. Use the Sine Rule: a s i n 113 ∘ = b s i n 21 ∘ = 9 S i n 46 ∘ b s i n 21 ∘ = 9 s i n 46 ∘ b = sin 21 0 x 9 /sin 46 0 = 4.484 cm a = sin 113 0 x 9 /sin 46 0 =11.517 cm.
