Question
Find $x$ in the figures.
✓
Answer
$x + 70^\circ + 60^\circ + (90^\circ + 90^\circ ) = 360^\circ [\because $ The sum of the measures of the exterior angles of any polygon is $360^\circ .]$
$\therefore x + 310^\circ = 360^\circ $
$\therefore x = 360^\circ – 310^\circ $
$\therefore x = 50^\circ $
$\therefore x + 310^\circ = 360^\circ $
$\therefore x = 360^\circ – 310^\circ $
$\therefore x = 50^\circ $
