Solution

$\small\fbox\pink{Sum\:of\:all\:angles\:in\:a\:triangle=180°}$

$\small\fbox\pink{Linear\:pair\:of\:angles=180°}$

______________________________________

First, lets find ∠ACB

⟼∠ACB = (180-60) (ʟɪɴᴇᴀʀ ᴘᴀɪʀ)

⟼∠ACB= 120°

Now, we have two angles that is 120°and 50°

Hence, the value of x is

⟼ 50°+120°+x=180° ( ᴀɴɢʟᴇ sᴜᴍ ᴘʀᴏᴘᴇʀᴛʏ)

⟼170°+x=180°

⟼x=180-170

⟼x= 10°
