Answer:
25 minutes
Step-by-step explanation:
he runs 4 laps in 8 minutes
so he runs 1 lap is 8/4 = 2 minutes
Therefore he rub 12.5 laps in 2 * 12.5 = 25 minutes
The equivalent of sec (-270) will be found as follows:
we add our angle to 360°
-270+360
=90
But sec(-270) is a positive value, this implies that the angle that will give us the same answer as sec (-270) should also give us the positive value. This means that 90 is our answer since it will give us the positive sec value.
The answer is d. sec(90)
Answer:
I don't really know how to show the work for this one but the answer should be 13 because angle CA is 8 too if Angles CA were to be rotated on to the X line BC it would like be almost about the same size as Anglesey are whatever and that what it would be like a few inches or whatever a few inches longer I guess
