Answer:
x = 26
angle QOR = 31
angle ROS = 59
Step-by-step explanation:

Sub x in

and

The quotient of x and three is 3/x. quotient is a division term and when the dividend is divided by the divisor, the result is a quotient.
The rate of change of the given equation is: 0.86
Step-by-step explanation:
Rate of change or slope is the steepness of a linear function or line.
When an equation is given in the form of slope-intercept form, the co-efficient of x is the slope or rate of change of the equation.
Given equation is:

We can see that the co-efficient of x is 0.86
Hence,
The rate of change of the given equation is: 0.86

We know that
[perimeter of rectangle]=2*(<span>length+width)
</span>
Let
x-----------> length
y-----------> width
so
P=2*(x+y)-----------> 244=2*(x+y)-----> x+y=122-------> y=122-x
Area=x*y-------> x*(122-x)----> 122x-x²
find the derivative function and equals to zero
122-2x=0-----> 122=2x----------> x=61 m
y=122-x------> y=122-61---------> y=61 m
<span>the maximum area is given by a square
</span>
the answer is
is a square of side 61 m
