Help I only have 15 minutes

central angle is COA

inscribed angle is CBA

angle COA=100 degrees

angle ABC=50 degrees

arc AC=100 degrees

Step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and
