Answer:
PV=20 QU=15 VS=26
Step-by-step explanation:
From what I understand, the line that crosses the centroid is normally separated into 3rds.
For example: QU is the full length, 3/3, and QV is 2/3 of QU. and VU is 1/3 of QU. If we know that QV is 10 then that means that 2/3 of that legment is 10.
10÷2=5
So, 5 would be 1/3 of QU. To find QU(3/3), you would need to multiply 5 by 3 which is 15.
Same thing applies for the other ones.
I hope this makes sense and helps you!
Answer:
Trapezoid
Step-by-step explanation:
Given quadrilateral has vertices at points A(-2,-1), B(3,13), C(15,5) and D(13,-11).
Find slopes of lines AD and BC:
Since the slopes are the same, lines AD and BC are parallel.
Find slopes of lines ABD and CD:
Since the slopes are different, lines AB and CD are not parallel.
This means quadrilateral ABCD is trapezoid (two opposite sides - parallel and two another opposite sides - not parallel)
Answer: The answer is 19.
Step-by-step explanation:
I took the quiz, and the correct answer to the question is 19.
I got 21% at selecting a point outside.
Explanation: Since the perimeter is 16sqrt (6), each side must be 4sqrt (6)
This also means that the diameter is 4sqrt (6).
To find the area of a circle, we need to find the radius (2sqrt (6)).
Area of circle is pi × (2sqrt (6))^2 = 24pi or approximately 75.4 units^2
Area of square is 4sqrt (6)^2 = 96
Thus, let's take the area of the circle and subtract that from the area of our square to yield approx. 20.6 units^2
and now divide through by 96 to yield 21%
Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees
We can rule out choice I since acut means less than 90
II is a possibility, but it doesn't best describe it
III. that is true, but it doesn't include the isocileese part
IV. that is true, but doesn't include the acute part
not sure, either III or IV
