90 miles driving at 45 mph for 2 hours
Solution:
As we know reference angle is smallest angle between terminal side and X axis.
As cosine 45 ° is always positive in first and fourth quadrant.
i.e CosФ, Cos (-Ф) or Cos(2π - Ф) have same value.
As, Cos 45°, Cos (-45°) or Cos ( 360° - 45°)= Cos 315°are same.
So, Angles that share the same Cosine value as Cos 45° have same terminal sides will be in Quadrant IV having value Either Cos (-45°) or Cos (315°).
Also, Cos 45° = Sin 45° or Sin 135° i.e terminal side in first Quadrant or second Quadrant.
60 miles per hour is the speed
The values of x and y are 2 and 0, respectively
The complete question is given below:-
−−→AB=(xy) a line is given in the question from the image given in the question What values should x and y take?
<h3>How do determine the value of x?</h3>
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
From the graph, we have the following highlights:
Point A is at:
A = 2
The point B is located at:
B = 0
The coordinate (x,y) is represented as:
(x,y) = (A,B)
So, we have:
(x,y) = (2,0)
Hence, the values of x and y are 2 and 0, respectively
