Answer 1

Let another angle be x

According to angle sum property

$\\ \rm\Rrightarrow x+35+78=180$

$\\ \rm\Rrightarrow x+113=180$

$\\ \rm\Rrightarrow x=180-113$

$\\ \rm\Rrightarrow x=67°$

Answer 2

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