QUICK I NEED HELP PLEASE!

Assuming you meant is $- \frac{3}{5} x+ \frac{1}{5} \ \textgreater \ 720$

The answer would be :
$- \frac{3}{5} x\ \textgreater \ 719.8$

$x \ \textless \ \frac{719.8}{ \frac{-3}{5} }$
$x\ \textless \ 719.8 *( \frac{-5}{3} )$
$x\ \textless \ \frac{-3599}{3}$

Hope this helps !

Measure of angle formed by two secants, from a point outside the circle is half the difference of the measures of the intercepted arcs.

m∠C = $\frac{1}{2}(m\widehat{AE}-m\widehat{BD})$
