# Math Help - Pythagoras Worded Problem Help

1. ## Pythagoras Worded Problem Help

I have this question, but I do not understand the wording of it.
For part a, I have used pythagoras to find y

$(4y)^2=180^2+50^2$
$(4y)^2=34900$
$4y=186.8$
$y=46.7cm$

Therefore $y$ = 467mm

Can someone help me with part b?

Nevermind, I worked it out by picturing the bigger right-angled triangles.
