1:6 slope will give as total angle of 19 degree being the arctangent 1/6 = 9.46 degrees and 1:8 slope = 14.2 degree being arctangent 1/8 = 7.125 degrees |

1:6 tu adalah ratio panjang sisi utk segi empat.. mcm gambar ni..
istilah slope 1:6 digune utk dptkn sudut θ..
utk cari θ, tan θ = 1/6
θ = arctan 1/6
= 9.46 |
