Question

value of angles

Answer 1

add up the arc measures BD and CE

then divide by 2

Answer 2

this will give you the measure of angle BFD

Answer 3

then you use the fact that

BFD + DFE = 180

Answer 4

Answer 5

nvm okay so 123 /2

Answer 6

which is 61.5

Answer 7

84+38 = 122

cut that in half 122/2 = 61

Answer 8

so angle BFD is 61 degrees

Answer 9

okay then what do with the 61?

Answer 10

that angle of 61 degrees adds to DFE and they add to 180

Answer 11

BFD + DFE = 180

61 + DFE = 180

Answer 12

180 - 61?

Answer 13

yes

Answer 14

alright so it's 119. Thank you so much ;)

Answer 15

correct, yw
