Given:
Four lines are marked proportion, the length of TW can be determined by
[tex]TW=a+4+b[/tex]
Value of a:
Let us set the proportion for the given lines.
Thus, we have;
[tex]\frac{a}{7}=\frac{4}{5}[/tex]
[tex]5a=28[/tex]
[tex]a=5.6[/tex]
Thus, the value of a is 5.6
Value of b:
Let us set the proportion for the given lines.
Thus, we have;
[tex]\frac{4}{5}=\frac{b}{5}[/tex]
[tex]20=5b[/tex]
[tex]4=b[/tex]
Thus, the value of b is 5.
Length of TW:
The length of TW is given by
[tex]TW=5.6+4+4[/tex]
[tex]TW=13.6[/tex]
Thus, the length of TW is 13.6
