Answer:

Difference in the length of AB and AD will be 1.17 units

Step-by-step explanation:

From the figure attached,

In ΔABC and ΔADC,

x = 45°

y = 63°

AC = 4 units

By applying Sine rule in ΔABC,

SinB = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

Sin(x) = [tex]\frac{AC}{AB}[/tex]

Sin(45)° = [tex]\frac{4}{AB}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{4}{AB}[/tex]

AB = 4√2 ≈ 5.657 units

Similarly, by applying sine rule in ΔADC,

Sin(y)° = [tex]\frac{AC}{AD}[/tex]

Sin(63)° = [tex]\frac{4}{AD}[/tex]

AD = [tex]\frac{4}{\text{Sin}63}[/tex]

     = 4.489 units

AB - AD = 5.657 - 4.489

             = 1.168

             ≈ 1.17 units

Therefore, difference in the length of AB and AD will be 1.17 units
