2 becuae......................................................................................................you have 5/10
It's C the missing side is 9 units long so since cosine is adjacent divided by hypotenuse it would be 9/41
Answer:
-1 every time
Step-by-step explanation:
Step-by-step explanation:
The formula is Distance=√(x2-x1)²+(y2 -y1)²
x1 is 5, x2 is 1, y1 is 9, y2 is 6
D = √( 1-5)² +(6-9)²
D = √(-4)²+(-3)²
D = √16+9
D = √25
D = 5 units
