diketahui :
x = 60
xb = 100
xa = 0
y = ?
yb = 180
ya = 30

[tex] \frac{y - ya}{yb - ya} = \frac{x - xa}{xb - xa} [/tex]


[tex] \frac{y - 30}{180 - 30} = \frac{60 -0 }{100 - 0} [/tex]
[tex] \frac{y - 30}{150} = \frac{60}{100} [/tex]

[tex]100(y - 30) = 150 \times 60[/tex]
[tex]100y - 3000 = 9000[/tex]

[tex]100y = 9000 + 3000[/tex]
[tex]100y = 12.000[/tex]
[tex]y = 120 \: derajat \: y[/tex]
