Magnitude 25411

There is a circle with a radius of 10 cm and its chord, which is 12 cm long. Calculate the magnitude of the central angle that belongs to this chord.

Correct answer:

A =  73.7398 °

Step-by-step explanation:

r=10 cm t=12 cm  sinA/2=rt/2  A1=2 arcsin(rt/2)=2 arcsin(1012/2)1.287 rad  A=A1  °=A1 π180   °=1.287 π180   °=73.74  °=73.7398=73°4423"
