Answer:
104°
Step-by-step explanation:
The principle to apply here is that angle subtended at the center of a circle is twice the angle at circumference.
Angle subtended at arc = 52°
Angle at the center = 2 x 52° = 104°
The range would be 14.
Explanation: you subtract the lowest and highest values in the set of data, which would be 1 and 15
<span><span>40. </span>115m
= An athlete trains per day
690m = total minutes of athlete’s training
d = number of days
=> 115(d) = 690
Now, the equation would be, 115 minutes per day to be multiplied by d or the
number of days to get 690minutes in all.
=> 690 / 115 = 6
=> 115 (6) = 690
d = 6
Therefore, an athlete trains 115 minutes in 6 days to get the total of 690
minutes in all.

Answer is 12/15 x 5/9 = 4/9
Step by step: first cross cancel to make your numbers to multiply smaller.
I divided 12 and 9 by 3 and 5 and 15 by 5, see attachment.
Then I multiplied across
