Question

Could someone please help me with this..?

Jerry inscribed a quadrilateral ABCD in a circle, as shown below.



If the measure of arc BCD is 250°, what is the measure of angle BCD?

70˚

75˚

55°

80°

Answer 1

55 :)

Answer 2

@ryan123345 do u mind explaining how..?

Answer 3

sure :)

Answer 4

thank u!!!! a million times!!

Answer 5

cuz im completely lost..

Answer 6

your welcome :) lol

Answer 7

ok so it tells you that arc BCD is 250.

Answer 8

since its and inscribed quadrilateral that means the angle opposite from BCD which is BAD is half. So from there u know that BAD is half of 250 so u know BAD is 75

Answer 9

no sorry not 75 lol

Answer 10

55?

Answer 11

half of 250 is 125. so than u know that BAD is 125

Answer 12

whoops..

Answer 13

than when u get that u know that in an inscribed quadrilaral opposite angles are supplimentary (add up to 180) so to find BCD u get 125 and subtract if from 180 to get 55 :)

Answer 14

wow. thank u sooo much are u in geometry too?

Answer 15

Your welcome. And yes im in honors geometry :D
