In circle N, KL ≅ ML.
What is the measure of Arc J M?
77°
90°
132°
154°

Answer:
es 132°
Step-by-step explanation:
KL ≅ ML, entonces triángulo KNL y NLM son similares ah Angle side Angle Theorom .
Entonces,{LNK ≅ LNM}
7x+7=8x-3 8x-7=7+3,x=10
13x+2=13*10+2=130+2=132°
La respuesta es 132°
Based on the relationship of the intercepted arcs of congruent chords, the measure of arc JM is: C. 132°.
If two chords are congruent, then the corresponding arcs bounded by the chords will have equal measure too.
Thus, KL = LM, therefore:
7x + 7 = 8x - 3
Solve for x
7x - 8x = -7 - 3
-x = -10
x = 10
Arc JM = 13x + 2
Plug in the value of x
Arc JM = 13(10) + 2
Arc JM = 132°
