Answer:

7π/18 radians

Step-by-step explanation:

A reference angle for angle β is the positive acute angle made by the terminal side of angle β and the x-axis.

A semi-circle angle has a measure of π radians.

The angle of the figure (in absolute value) can be decomposed as the addition of its reference angle and π radians. Therefore:

π + reference angle  = 25π/18

reference angle  = 25π/18 - π

reference angle  = 7π/18 radians

Rectangular classroom seats 72 students. If the seats were rearragned with 3 more seats rows in each row, the classroom would ha
Gre4nikov [31]
<span>Let the original number of seats in a row be x;
</span>Let the number rows be y;

( x + 3) * (y - 2 )= 72 and x * y = 72 => 72 + 3 * y - 2 * x = 72 => 3 * y = 2 * x;
=> x is divisible by 3;

1. x = 3 => y = 72 / 3 => y = 24;
2. x = 6 => y = 72 / 6 => y = 12;
3. x = 9 => y = 72 / 9 => y = 8;
4. x = 12 => y = 72 / 12 =. y = 6;
5. x = 24 =. y = 72 / 24 => y = 3;
6. x = 36 => y = 72 / 36 => y = 2;
7. x = 72 => y = 72 / 72 => y = 1;

My analysis tell me that the right answer is 9 seats in a row and 8 rows;
The original number in each row is 9.
