Answer:
- arc BC: 8.55 cm
- chord BC: 8.03 cm
Step-by-step explanation:
The length of an arc that subtends central angle α will be ...
s = rα . . . . where α is in radians
The central angle BOC is twice the measure of angle QBC, so is 70°, or 7π/18 radians. So, the length of arc BC is ...
s = (7 cm)(7π/18) ≈ 8.55 cm . . . arc BC
__
For central angle α and radius r, the chord subtending the arc is ...
c = 2r·sin(α/2)
c = 2(7 cm)sin(35°) ≈ 8.03 cm . . . . chord AB
The answer is gonna be 14
△ABC is similar to △LMN by the AA Similarity Postulate . The measure of ∠A is 111º and m∠C=2(m∠M).
Since the Angle of A is 111 degrees.
Another angle, Angle of C is twice the angle of M.
Angle of A = Angle of C
2 (Angle of M) = Angle of C
2 (Angle of M) = 57
<span>Angle of M = 28.5 degrees</span>
