the following diagram shows a circle with center \(\displaystyle O\) and a radius
\(\displaystyle 4cm\)
View attachment 1006
The points \(\displaystyle A, B,\) and \(\displaystyle C\) Lie on the circle.
The point \(\displaystyle D\) is outside the circle, on \(\displaystyle (OC)\)
Angle \(\displaystyle ADC=0.3\) radians and angle \(\displaystyle AOC=0.8\) radians
(a) find \(\displaystyle AD\)
I used law of sines
\(\displaystyle \frac{4}{\sin{0.3}}=\frac{x}{\sin{0.8}}\)
\(\displaystyle x \approx 9.71cm\)
there are more questions to this but want to make sure this is correct
\(\displaystyle 4cm\)
