Can someone help me, please I've been getting so many wrong if you get it right I'll give brainiest

<YWX=30°; YX=80÷2=40

WX²+40²=80²

WX²=6,400-1,600

WX=√4,800=√(4×4×4×25×3)=40√3

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
