In the diagram below, determine the value of $x$: [asy]
size(6.5cm);
pair cis(real magni, real argu) { return (magni*cos(argu*pi/180),magni*sin(a rgu*pi/180)); }

draw(cis(1.5,15)--cis(-1,15)--cis(- 1,15)+cis(2.5,-15));
draw(cis(-1,60)--cis(1,60)--cis(1,6 0)+cis(2.2,-75));
label("$30^\circ$",cis(-1,15)+(0.2, 0),E);
label("$45^\circ$",cis(1,60)+(-0.05 ,-0.2),S);
label("$130^\circ$",(-0.03,0.03),SE );
label("$x^\circ$",(0.8,-0.64));

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
