Answer:
True; quadrants I & IV
Step-by-step explanation:
We know the relation between sine and cosine function which is given by

Let us solve this equation for cosine function.

Take square root both sides. When ever we take square root we need to write the solution in plus minus form



If Θ is in quadrants I and IV then the value will be positive and if Θ is in II and III quadrant then the value is negative.
Hence, if Θ is in quadrants I & IV, then we have

Thus, the correct option is: True; quadrants I & IV
Answer: 4/10
Explanation: 9/10 - 5/10 = 4/10
The denominator is already both 10 so u can subtract the numerator without worry
