anyone willing to do an online geometry course?(has to be a smart person)

OpenStudy (anonymous):

how smart??

OpenStudy (anonymous):

It's probably best to try to do it on your own and come here if you need any help. If someone else does the course, you won't learn anything.

OpenStudy (anonymous):

i agree with @futrchamp

OpenStudy (anonymous):

but i need to finish it its a 10th grade course

OpenStudy (anonymous):

is this course by flvs.net?

OpenStudy (anonymous):

no its an oddysware course

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

You're gonna need to work on it and come here when you get stuck.

OpenStudy (anonymous):

yes, come here like at any time

OpenStudy (anonymous):

OpenStudy (anonymous):

You can copy and paste them

OpenStudy (anonymous):

You can also take screenshots of them.

if a triangle is a right triangle, then the other 2 angles must be acute? true or false

OpenStudy (anonymous):

True. This uses the triangle sum theorem. 90 + x + y = 180 x + y = 90 See?

OpenStudy (anonymous):

the three sides of an equilateral triangle measure x+12,2x-5 and 3x-22 inches. the sides of the triangle measure?

OpenStudy (anonymous):

the sum of the measures of the interior angels in a polygon is 540 degrees. How many sides does the polygon have?

OpenStudy (anonymous):

Set them equal to each other since equilateral triangles have three equal sides. x + 12 = 2x - 5 x = 17 Plug this back in for x in the following and that will be the measure of one of the sides. x + 12 = 17 + 12 = ?

OpenStudy (anonymous):

Nevermind, I read the question wrong

OpenStudy (anonymous):

Second Problem: \[\text{Sum of the measures of all interior angles} = (n - 2)180\]\[540 = (n - 2)180\]Solve for n here.

OpenStudy (anonymous):

find the area of a parallelogram with sides of 12 inches and 8 inches if one of the angles is 120 degress? options are: A.48sqinches B.48squareroot3squareinches C.96

OpenStudy (anonymous):

for this one its going to be base times height. 12*8=96

OpenStudy (anonymous):

wrong
