    Let another angle be x
    According to angle sum property
    [tex]\\ \rm\Rrightarrow x+35+78=180[/tex]
    [tex]\\ \rm\Rrightarrow x+113=180[/tex]
    [tex]\\ \rm\Rrightarrow x=180-113[/tex]
    [tex]\\ \rm\Rrightarrow x=67°[/tex]

    67°, every triangle equals 180° so add together 35+78 which equals 113. subtract 180-113 and get 67!
