There are many ways to do this.
If B is the top center then all three are true
Answer:
(64/5)π
Step-by-step explanation:
Area of the circle: 16π
central angle: (8/5)π
The Area of the circle corresponds to a central angle equal to 2π (the complete circle). Then the following proportion must be satisfied:
16π / x = 2π / (8/5)π
x = [16π * (8/5)π] / 2π
x = (64/5)π
The measurement of the second angle is 42°. All of the angles of a triangle add up to a total of 180°. If two angles add up to 138°. Then the last angle has to be 42° (180-138).
You should ask your parent/guardian or teacher if needed! Merry Christmas!
