Anyone good at angles?

OpenStudy (anonymous):

I can try to help

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

what do you need help with

OpenStudy (anonymous):

I'll put it up

OpenStudy (anonymous):

HanAkoSolo (jamierox4ev3r):

well angles 2,3, and 5 are all parts of a triangle. And all triangles have 180 degrees, so therefore, angles 2, 3, and 5 should all add up to 180 degrees. Also, since the two lines are parallel, there are a lot of calculations that can be done

OpenStudy (anonymous):

so what does that mean?

OpenStudy (anonymous):

but no reason to complicate anything. all you need to know for this problem is that all angles in a triangle add up to 180

HanAkoSolo (jamierox4ev3r):

so here are a few hints: |dw:1430762751813:dw|

OpenStudy (anonymous):

so just put any numbers as long as they add up to 180

HanAkoSolo (jamierox4ev3r):

|dw:1430762804761:dw|

HanAkoSolo (jamierox4ev3r):

but as @FlashBT3 has said, since it is a triangle, triangle angles will always add up to 180 degrees

OpenStudy (anonymous):

for a triangle yes bigger number will be the bigger angle smallest number is the smallest angle middle number is the 2nd biggest angle

HanAkoSolo (jamierox4ev3r):

|dw:1430762880590:dw|

OpenStudy (anonymous):

@Jamierox4ev3r is right with all that I just try to keep things simple

OpenStudy (anonymous):

cool

OpenStudy (anonymous):

so do you mind checking some of my answers?

OpenStudy (anonymous):

no problem

OpenStudy (anonymous):

ok wait a sec

OpenStudy (anonymous):

I put 39 for that one

OpenStudy (anonymous):

66 for this one

OpenStudy (anonymous):

I put B. but I'm not sure

OpenStudy (anonymous):

since they are both labeled x they are equal to each other, so do 180-102=78 then divide by 2 = 39 for each of the angles in the 1st question

OpenStudy (anonymous):

2nd one 66 is right

OpenStudy (anonymous):

I put B for this one too,but I'm not sure

OpenStudy (anonymous):

This one goes with #5 I put B,but then again I'm not sure

OpenStudy (anonymous):

3rd one is wrong. again it is just a triangle just add up the angles it gives you 14+32=46 then subtract that from 180-46=134

OpenStudy (anonymous):

ok :)

OpenStudy (anonymous):

4th one is right

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

the last one is C because they do not share a line.

OpenStudy (anonymous):

ok cool thanks

OpenStudy (anonymous):

yw

OpenStudy (anonymous):

I have a couple of more I need reassuring on

OpenStudy (anonymous):

@FlashBT3

OpenStudy (anonymous):

a straight line is also equal to 180 degrees and 63 and 3 are corresponding so they are equal. since now you know 3=63 you can do 180-63 to get your answer for the first one

OpenStudy (anonymous):

117

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

so I'd put that under angle three?

OpenStudy (anonymous):

yes
