(5/18) out of 18 = (5/18) ÷ (18/1) = (5/18) * (1/18) = (5*1) / (18*18) = 5/324 ;
5 ÷ 324 = 0.0154320987654321 ;
0.0154320987654321 * 100 = 1.543208 % ;

Answer:
Solution given:
Y=90°
∠X=73°.
∠ZWY=80°
and XW=80.
ZY=?
We know that
In right angled triangle ∆ XYZ
Tan 73=
3.27=
3.27×[xy]=yz
xw+wy=
wy=-80...........(1)
again
In right angled triangle WYZ
Tan 80=
5.67×wy=yz
wy=
yz=5.67×wy............................................(2)
Equating equation 1&2
=
-80
-
=80
5.67yz-3.27yz=80*5.67*3.27
2.4yz =1483.272
yz=
yz=618.03
:.y=618.03unit.the length of ZY to the nearest 100th is 618.
