we say that 2 is to side of length 4, the same as m is to side lengths 10. And in math terms:
Answer:
Step-by-step explanation:
a = 77 m
b = 72 m
c = Distance between the tugboats = 35 m
= Angle between the cables
The angle formed between the cables is .
2 mi
The bigger triangle is 3 times larger than the smaller one
I’m pretty sure it’s this
