2. Write an inequality relating the given side lengths. It is possible that there is not enough information to reach a conclusion. Fill in the blank with: <, >, =, or NC (no conclusion). (***I thought the answer was > but my teacher said this one was wrong as well. Can someone help me correct it.***)

jimthompson5910 (jim_thompson5910):

hint: this is another hinge theorem problem. Just think in reverse. You're given opposite sides to angles we want to compare

jimthompson5910 (jim_thompson5910):

another hint: compare segments ST and MP

OpenStudy (cookiemonster18):

ST is 15 degrees and MP is 14 degrees @jim_thompson5910

jimthompson5910 (jim_thompson5910):

ST is a length not an angle MP is a length not an angle

OpenStudy (cookiemonster18):

:/....so how do I solve them is they aren't angles?

jimthompson5910 (jim_thompson5910):

which is larger? ST or MP?

OpenStudy (cookiemonster18):

ST

jimthompson5910 (jim_thompson5910):

so the angle opposite ST is larger than the angle opposite MP R > L

jimthompson5910 (jim_thompson5910):

just think "hinge theorem in reverse"

jimthompson5910 (jim_thompson5910):

angle R > angle L angle L < angle R

OpenStudy (cookiemonster18):

sooo??? that means < is the answer to solving this problem? I don't get it....

jimthompson5910 (jim_thompson5910):

yes you just put a less than sign

jimthompson5910 (jim_thompson5910):

where are you stuck?

OpenStudy (cookiemonster18):

I wasn't sure why it had to flip and change amounts with each other....

jimthompson5910 (jim_thompson5910):

you mean the flip here? angle R > angle L angle L < angle R

OpenStudy (cookiemonster18):

yes

jimthompson5910 (jim_thompson5910):

I just rearranged L and R

OpenStudy (cookiemonster18):

oh....okay, well can we do 3?...i'll start a new one
