Based on the inscribed quadrilateral conjecture: trapezoid QPRS can be inscribed in a circle because its opposite angles are supplementary.
<h3>What is the Inscribed Quadrilateral Conjecture?</h3>
The inscribed quadrilateral conjecture states that the opposite angle of any inscribed quadrilateral are supplementary to each other. That is, they have a sum of 180 degrees.
From the diagram given, the opposite angles in the trapezoid, 115 + 65 = 180 degrees.
Therefore, we can conclude that: trapezoid QPRS can be inscribed in a circle because its opposite angles are supplementary.

X= 3 because the absolute value makes the -5 a 5. Meaning it will be x+5=8 and then you just solve for x
Answer:
Step-by-step explanation:
Average speed = total distance / total time taken
Average speed is the total distance traveled divided by the total time taken
The carrier first odometer route is
d_1 = 31,500 miles
On return of the truck, the odometer reads
d_2 = 31,713 miles
The total time taken is 6.5 hours on return
Then,
Average Speed = total distance / total time.
A.V = (d_1 + d_2) / t
A.V = (31,500 + 31713) / 6.5
A.V = 63213 / 6.5
A.V = 9725.1 mile per hour
A.V = 9725.1 mph
