B. -5
F(-1)=2x-3
=2(-1)-3
=-2-3
=-5
Answer:
obtuse angle
Step-by-step explanation:
5/10 is equal to 25/50
I ts because you multiply 5x5 to get 25 and do the same to the denominator so 10x5 is equal to 50 so 25/50 is the answer.
For n=2,
put the value 2 in the above equation we get 525*2=1050°.
1050° angle takes 2 complete revolution and then makes an angle of 330° which will fall in the negative portion of y-axis.
For n=6,
put the value 6 in the above equation we get 525*6=3150°.
3150° angle takes 8 complete revolution and then makes an angle of 270° which will fall along negative y-axis.
