Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = = = ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = ≈ 19.4 cm ( to 3 significant figures )
Answer:
77
Step-by-step explanation:
Step-by-step explanation:
arccos(sin(5π/4))
= arccos(sin(-π/4))
= arccos(-√2/2)
= 3π/4.

Juan ate 1/3
Jelly beans remaining = 1 - 1/3 = 2/3
Maria ate 3/4 of the remaining = 3/4 x 2/3 = 1/2
Jelly beans remaining = 2/3 - 1/2 = 1/6
1/6 of the jelly beans = 10
Total number of jelly beans = 10 x 6 = 60
Answer : There are 60 jelly beans in the bag at first.
