@vocaloid

Vocaloid:

I got something a little different. what did you get when you solved for x?

Vocaloid:

<AFC and <BFC are vertical angles, correct? that means they're equal and you can set them equal to each other to solve for x. once you have x you can plug back into m<ACF = 10x - 11 to get this measurement

Gucchi:

okay wait a sec i think i did the math wrong

Vocaloid:

10x - 11 = 6x + 9 4x = 20 x = 5 plugging x back into (10x-11) gives us 39

Gucchi:

so sorry i had to go do something 😭i did the math myself again and it came out as 39. i think i messed up with the equation at first.

Gucchi:

thank you again
