Please help me answer this question, it was due yesterday .​

Answer 1

Answer:

FA=7.29

Step-by-step explanation:

$FD=\sqrt{10^{2}-8^{2} } \\FD=\sqrt{36} \\FD=6$

∠EDF=53° (properties of retangle)

∠EAD=180-90-53 (∠ sum of Δ)

          =37

$\frac{AD}{sin90} =\frac{8}{sin37} \\AD=13.29$

FA=AD-FD

FA=7.29
