Answer:

BC ≈ 11.9 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin58° = \frac{opposite}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{14} ( multiply both sides by 14 )

14 × sin58° = BC , then

BC ≈ 11.9 cm ( to 1 dec. place )

Ugo [173]

Answer:

{2,8}

Step-by-step explanation:

This is the same thing as asking what element (in this case what number) is in all 3 sets.

0 isn't in all 3 sets because it isn't in B.

2 is in all 3 sets

3 isn't because it isn't in C

4 isn't in A.

6 isn't in C.

8 is in all 3 sets.

9 isn't in A

So the elements that are in the 3 sets are {2,8}.
