Mathematics

Find the values of the unknowns $x$ and $y$ in the figure (i).

$x=70, y=60$

SOLUTION
$y=120=180$, since they form a straight line.

Therefore, $y=180-120$

$\Rightarrow y=60$

$x+y+50=180$, since they form a triangle

$x+60+50=180$

$x=180-60-50$

$\Rightarrow x=70$

You're just one step away
