Coordinates of point A are
(-3,-2)
Origin lies in the center of coordinate system. That means that you can picture this as right triangle with sides 3 and 2 and you need to find hypotenuse of it.
Using pythagoras theorem we calculate:
h^2 = 3^2 + 2^2 = 13
h = sqrt 13
<span>Answer is b</span>
sin α = opposite leg/ hypotenuse
For ΔABC,
sin A = |BC|/|AB|
sin A = 12/37
Answer: 5
Step-by-step explanation: 6/7+ 6 each = 12/13
Multiply both sides by -1
|-x|=12
-x=12
x=-12
-x=-12
x=12
Final answer: D
