Question

Letter b on number 11 is all I need help with. Thank you

Answer 1

distance = 500 feet

Since Δ VWX and Δ YZX are similar then the ratios of corresponding sides are equal, that is

$\frac{VW}{YZ}$ = $\frac{VX}{YX}$ = $\frac{WX}{ZX}$

completing the required values gives

$\frac{100}{l}$ = $\frac{60}{30}$ ( cross- multiply )

60l = 30 × 100 = 3000 ( divide both sides by 60 )

l = 500

distance across the swamp is 500 feet
