Answer 3

okay thanks

Answer 4

so this is an angle inscribed in a angle correct?

Answer 5

so the angle inscribed in a circle is naturally equal to 1/2 of the subtened arc aka the blue area labeled 130degrees, so 130/2 = 65, 65 should be your answer

Answer 6

IN ABC the middle point is the center of your angle, so B is your angle.

Answer 7

in other cases DBE the opposite angle will be 1/2 of 40 meaning DBE is 20 degrees

Answer 8

and the other angles with red arcs are 95degrees, so if you add up 95 + 95 + 40 + 130 you get 360, meaning that the other two angles are equal to 47.5 degrees
