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.
Answer:
A
Step-by-step explanation:
50 percent is 50/100 and you are trying to find x which is half of 70. A would make the most sense. X should =35

Answer:
A. How many paperback books each person buys.
Step-by-step explanation:
In the equation the x represents how many paperback books they can buy.
In the equation the 2 represents that 1 hardcover book was purchased.
In the equation the 35 represents how much money they spent in total.
The equation is complete except for x which has to be substituted with how many paperback books they can buy. Which would be 5.
