Answer 5

start by finding the value of "x"

Answer 6

since the AC is the diameter, it is also a straight line, so the angles add up to 180 :

\[6x+5x+8x = 180\]

solve \(x\)

Answer 7

x=10?

Answer 8

@rational

Answer 9

try again

Answer 10

oh sorry is it x = 2?

Answer 11

how ?

Answer 12

this is how i solved it

Answer 13

\[6x+5x+8x=180\]
\[19x=180\]
\[x = \dfrac{180}{19} = 9.47\]

right ?

Answer 14

6x + 5x + 8x = 180
19x = 180
x = oooohhh i calculated wrong xc

Answer 15

thats okay multiply that x by 8 to get the measure of angle CQD

Answer 16

i just resolved it and i got 9.47

Answer 17

good multiply that by 8

Answer 18

75.76

Answer 19

Yep!

Answer 20

maybe multiply it without rounding

Answer 21

180/19*8 = ?

Answer 22

so the answer would be B

Answer 23

75.79

Answer 24

thats right!

Answer 25

thanks alot!
