The answer is (15,0) because the format is (x,y) so (15,0) means that it is on the x axis only !
Answer:
it's angle 1.
Reason:
vertically opposite angles are equal
The angles around the point a total 360°
the lines AB and AC make a sector of the circle.
we are told that the circumference of that sector is 2/5 of the total circumference
so 360/5 ×2 =144
