Add up all the lengths of the garden and you will be able to get the perimeter.
The magnitude of the vector is √(7^2+12^2)=√(49+144)=√193
The direction is α=arctan(y/x)=arctan(12/-7)≈-59.74 however this is relative to the negative x-axis so we add 180° to get the standard angle...180-59.74=120.26°
So the vector is √193 @ 120.26°
If it’s asking if it’s true of false it’s false
Because 5/11x6/7 =30/77
Answer:
90°
Step-by-step explanation:
note that 
simplifies to 
There are 360° in one turn of the circle , then
× 360° = 360° ÷ 4 = 90°
