Answer:
1/3 I think I did the math and if that's not right try 1/3:1/4 (<--ratio)
Step-by-step explanation:
Using cosine law,
d^2 = 65^2 + 35^2 - 2(65)(35)cos140
= 8935.5022
d = sqrt(8935.5022)
= 94.5 m
Angle = inverseCos(35sin40 / 94.5) = 76.23 degrees South of East
Answer:
The ratio 2 1/2 to 6 1/2 is

Step-by-step explanation:
Ratio:
In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second.
