Question

select the correct answer from each drop - down menu. consider right triangle abc. image of right triangle abc with ab = 40, bc = 9, ac = 41, right - angled at b sin(a)= drop - down = drop - down cos(a)= drop - down = drop - down (drop - down options for cos(a) include tan(c), cos(c), sin(c), tan(a), sin(a))

Explanation:

Step1: Identify sides for angle A

Right triangle ABC, right-angled at B. For angle A: opposite side = BC = 9, adjacent side = AB = 40, hypotenuse = AC = 41.

Step2: Calculate sin(A)

sin(A) = opposite/hypotenuse = 9/41

Step3: Calculate cos(A)

cos(A) = adjacent/hypotenuse = 40/41

Answer:

sin(A) = opposite/hypotenuse = 9/41
cos(A) = adjacent/hypotenuse = 40/41
