1. Construct the bisector of .
Construct the circle that circumscribes .
3. Find the area of sector GHJ, given that . Express your answer in terms of and rounded to the nearest tenth.
Here is a YouTube video explaining the procedure for (1)
And here's another one for (2)
3) We have to know the measure of θ before we can provide a definite answer
But....the area is given by
(1/2)* radius^2 * θ if θ is in radians
pi * radius^2 * (θ / 360) if θ is in degrees
