The size of ∠QTW in degrees is 72°. See the explanation below. This is based on the concept of opposite sides in a quadrilateral.
<h3>What is the logic leading to the above result?</h3>
QSUWY which is a pentagon is regular that mean:
∠QYW = 108°
The quadrilateral QTWY is a cyclic one. This means that we can apply the rule that states that opposites sides must add up to 180°
Thus, ∠QTW =
180 - 108
= 72°
<h3>What is a quadrilateral?</h3>
A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon.
In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

Answer:
Step-by-step explanation:
The density of water is given by the following definition:
The density is maximum when volume is minimum, which can be found by First and Second Derivative Tests:
First Derivative
Second Derivative
Critical values from the first derivative are:
(absolute maximum) and (absolute minimum).
The temperature at which water has its maximum density is:
Answer:
10y
solve. you need to combine like terms and subtract.
I need to know the numbers to be able to answer.
Y=2x+4, the slope is 2, A(0,4)-y intercept
y=x+2, the slope is 1, B (0,2)- y intercept
the system is 2x-y=-4
-x+y= 2
-----------
x= -2
y=0 is the solution ( only one)
