B. The correct ratio is sen α = BC/b. Step-by-step explanation: Trigonometric identities are utilized for resolving problems involving right angles. In any right-angled triangle, the side opposite to the angle is known as the opposite side, while the adjacent side runs parallel to the angle, ultimately leading to the longest side, called the hypotenuse.
Answer:
You need to multiply the denorminator both sides in order to form x note the subject:
Since the angles are complementary, it follows that sin A = cos B and sin B = cos A
therefore sin A + sin B = 0.55 + 0.83 = 1.38
