Does m mean “minor” angle/arc/sector as opposed to reflex/major

frank charm
#

im pretty sure the "m" means 'measure'

#

"m<AMR" in other words"measure of angle AMR"

sweet kelp
#

Idk what that means, can I call it “value of angleAMR”

frank charm
#

arent they the same?

sweet kelp
#

If they’re the same then sure ill think of it as value

#

Cuz no one around me used such notation

frank charm
#

sure

#

i still need help 😭

#

i forgot what formula to use to find x

sweet kelp
#

angle at center is twice the angle at circumference

frank charm
#

it doesnt't help with fiding x

sweet kelp
#

it does when you know what angleASR is

frank charm
#

<amr is 3x+20, <omr is x+30

k wait

#

im stuck too

#

thats odd, angleAMR should = angleOMR, but this would violate the "AROS is a rhombus" condition

how can MR not be a diameter if S is the center

olive crown
sweet kelp
#

given (center symbol) S, ...

olive crown
sweet kelp
#

you mean MR doesnt pass through S?

olive crown
#

it's not necessarily opposite to R

sweet kelp
#

or MSR isnt a single straight segment

otherwise the initial statement is contradictory

sweet kelp

#

it just impies that angle AMO=60

sweet kelp
#

how could angleASR and angleOSR not be 60 tho

olive crown
#

and that (3x+20)+(x+30)=60

olive crown
sweet kelp
#

since angleASR is 60 angleAMR is 30, and since angleOSR is 60 angleOMR is 30

olive crown
#

ngleAMR is NOT 30,

sweet kelp
#

M can move anywhere on majorarcAR and this would be valid

sweet kelp

#

Oh, yes, I'm wrong

#

so, yes, the statement is contradictory in any case

sweet kelp

alr cool

olive crown
#

then we have 3x+20=30 and x+30=30.

#

x=10/30=0 🙂

#

maybe M is above AO?

sweet kelp
#

tbh i never saw chords labelled equal using the triangle congruent sign

yep. something is not ok with the statement.
