Answer:
68.5
Step-by-step explanation:
Angles DEC and DAC are right angles, so their sum is 180°. DECA is a quadrilateral, which has a sum of interior angles equal to 360°. Then angle ACE is the supplement of angle D:
∠ACE = 180° -43° = 137°
Inscribed angle ABE has half the measure of central angle ACE, so we have ...
x° = 137°/2
x = 68.5
8 · 7 = 56, therefore LCM(8, 56) = 56.

Answer:
Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.
θ= 40° = 0.698 rad
Let R be the radius of circle.
Chord Length = 2Rsin(θ/2)
12=2R sin (0.698 /2)
R= 17.54
Ans: Radius of circle = 17.54 cm
