its x=45 or 45 degrees

So to write this down in an equation it would be $y=3z$
and $y=180 - x$ and $z=90-x$

x is the unknown angle in question

and y is its suppliment while z is its compliment

soooooooo write it $y=3z$ and ya get

now lets simplify this down a tad

$180-x=3(90-x)$
$180-x=270-3x$
$-x+3x=270-180$

$2x=90$
$x=45$
