ooooh yeah from the Transformation lesson forgot about that
KQ= 16 * 14/8
KQ= 28
NQ= 28 - 16
NQ = 12
#27 Re: Help Me ! » Geometry review » 2012-12-16 00:21:21
a bet confused because I don't remember taking dilation but
triangle KPN I get the following information :
opposite = 13.8564
hypotenuse = 16
adjacent = 8
and I get a 90 60 30 angle
#28 Re: Help Me ! » Geometry review » 2012-12-15 11:41:08
So I can use the Pythagoras theorem
14²+ b²= 16²
196+ b² = 256
256- 196=b²
b²= 60
b= 2√15 or 7.75
#29 Re: Help Me ! » Geometry review » 2012-12-15 11:24:31
Ok So can I cut the trapezoid into a square and a right triangle?
So the triangle side would be 8
10. In the diagram shown,line PN is parallel to line JQ , KN =16 centimeters, PN= 8 centimeters, and JQ = 14 centimeters. Determine the length of line NQ.
A 28 cm
B 12 cm
C 9.1 cm
D 7 cm

Hi,
I got C as an answer wondering if that is correct
7. The apothem of a regular 9-sided figure is 6 feet and the area is 117.67 square feet. What is the perimeter of the regular 9-sided figure?
A 4.36 feet
B19.61 feet
C39.22 feet
D54.00 feet

I sure do lol.
Thanks for helping
#38 Re: Help Me ! » Proof » 2012-12-13 11:56:09
No I didn't plot them 
probably why I got the question wrong the don't make a square or a right triangle So both (unfounded)
#39 Re: Help Me ! » Proof » 2012-12-13 11:16:00
2 more left
I answered C for both it was incorrect
19. The given points (4, -8), (4, -5), and (-2, -6) make a right triangle.
A Distance Formula
B Definition of a right triangle
CDefinition of a triangle
Dunfounded
E Pythagorean Theorem
F Definition of radius
20. The given points (2, -3), (-7, -7), (2, -7), and (-7, -2) make a square.
A Definition of coordinate
BPythagorean Theorem
CDefinition of a square
DDefinition of supplementary angles
E Distance Formula
F unfounded
#40 Re: Help Me ! » Proof » 2012-12-13 08:23:42
No the radius isn't cut into equal parts so that whole statement is incorrect So C would be a good answer
#41 Re: Help Me ! » Proof » 2012-12-13 07:34:26
E was incorrect I still don't see why O_o
16. If a radius bisects a chord, then the lengths of the parts of the radius on either side of the chord are equal.
A Given
BDefinition of a chord
Cunfounded
DDefinition of supplementary angles
E Definition of a bisector
F Definition of radius
#42 Re: Help Me ! » Proof » 2012-12-13 07:33:10
yeah I was stuck on which one to choose to. lol
#43 Re: Help Me ! » Proof » 2012-12-13 07:10:51
I choose E and it was incorrect
my new answer is D
14. If a central angle is 30 degrees, then the arc it defines is also 30 degrees.
A Given
BDefinition of an inscribed angle
Cunfounded
DProperties of a central angle
E Properties of an arc
F Definition of radius
#44 Re: Help Me ! » Proof » 2012-12-13 05:16:55
So B would be a good answer ?
#45 Re: Help Me ! » Proof » 2012-12-13 05:15:48
no EJ ≠ Jm
#46 Re: Help Me ! » Proof » 2012-12-12 12:36:58
yup 14/ 20 
The lesson uses the same chart for all the questions that use the chart
#47 Re: Help Me ! » Proof » 2012-12-12 09:30:23
I am still confused on what am really doing 
I got 6 incorrect out of 20 
I choose A and it was incorrect
7. In the figure above, line segment EJ is equal to line segment JM
A Definition of radius
Bunfounded
CDefinition of an octagon
D1267200 inches
E Given
F Definition of supplementary angles
#48 Re: Help Me ! » Proof » 2012-12-12 07:29:35
Hi,
According to my online courses A plane is defined by any of the following:
three points not lying on a line
a line and a point not lying on the line
two lines which intersect in a single point or are parallel
So I think C would be a correct answer
#49 Re: Help Me ! » Proof » 2012-12-12 06:04:12
I have to use the information I know to proof the statement correct
#50 Re: Help Me ! » Proof » 2012-12-12 06:02:55
I answered A and it was incorrect .
Yeah this lesson is confusing but I did answer 14 correctly like this one :
(F ) was correct
6. In the figure above, line segment MC is equal to imaginary line segment MI.
A Given
Bunfounded
CDefinition of supplementary angles
D1267200 inches
E Definition of an octagon
F Definition of a circle: all points are equidistant from the center
