Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° = , cos45° = , thus
sin60° = = = ( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp =
Now consider the right triangle on the right, using the cosine ratio
cos45° = = = ( cross- multiply )
x = × = → C
I think it is 2,504.
when you round 2,505 it comes out to 2,510.
Answer: 34.2
For everyone 1 kilometer=.621371 so if you times that by 55 you get 34.1754 which rounds to 34.2
