1.25 is the length x of a side of the square. Think about it like this. Divide 25 by 16 and you get 1.5625. Then, you do that number squared. So, √1.5625. That gives you 1.25. Hope that helps! Good luck!
See the attached for a graph and the solution: (x, y) = (3, 0).

With the availability and simplicity of the Desmos on-line graphing calculator, this is my favorite method of solving systems of equations.
Answer:
7pi/2
Step-by-step explanation:
Given the expression cosec x = -1
I'm trigonometry csecx = 1/sinx
The equation becomes
1/sin(x) = -1
Sinx = -1
x = arcsin(-1)
x = -90°
x is negative in the third and 4th interval
Third interval;
x = 180+90
x = 270°
x = 3pi/2
Since the angle should be within 3pi < x < 4pi
Add 2pi to the angle
x = 2pi+ 3pi/2
x = 7pi/2
Hence the required angle is 7pi/2
The perimeter of a rectangle is all sides added up, so length + length + width + width.
L = length
W = width
then the perimeter is L+L+W+W, or 2L + 2W, or 2(L+W).

what's the length? well, is just
2(27).
