Step-by-step explanation:

sᴏʟᴜᴛɪᴏɴ →

ғɪʀsᴛ ᴡᴇ ʜᴀᴠᴇ ᴛᴏ ʟᴀʙᴇʟ ᴛʜᴇ ᴅɪᴀɢʀᴀᴍ

ᴀɴɢʟᴇ 'ᴀʙᴄ' = 30°

ᴀɴɢʟᴇ 'ʙᴀᴄ' = 90°

ᴀɴɢʟᴇ 'ᴀᴄʙ' = x

ᴀs ᴡᴇ ᴋɴᴏᴡ ᴛʜᴀᴛ sᴜᴍ ᴏғ ᴀʟʟ ɪɴᴛᴇʀɪᴏʀ ᴀɴɢʟᴇ ɪs 180

ᴛʜᴇʀᴇғᴏʀᴇ :-

30°+90°+x( ᴀɴɢʟᴇ 'ᴀᴄʙ' ) = 180°

120° + x = 180°

x= 180°-120°

x= 60°

ᴀɴɢʟᴇ 'ʏ' ᴀɴᴅ ᴀɴɢʟᴇ 'x' ᴀʀᴇ ʟɪɴᴇʀ ᴘᴀɪʀ

sᴏ ᴡᴇ ᴄᴀɴ sᴀʏ ᴛʜᴀᴛ

-

ᴀɴɢʟᴇ 'ʏ'+ᴀɴɢʟᴇ 'x' = 180°

ᴀɴɢʟᴇ 'ʏ' = 180°- ᴀɴɢʟᴇ 'x'

ᴀɴɢʟᴇ 'ʏ' = 180°- 60°

ᴀɴɢʟᴇ 'ʏ' =120° ᴀɴs.
