\bf \sqrt{28}\cdot \sqrt{176}~~ \begin{cases} 28=2\cdot 2\cdot 7\\ \qquad 2^2\cdot 7\\ 176=2\cdot 2\cdot 2\cdot 2\cdot 11\\ \qquad 2^2\cdot 2^2\cdot 11\\ \qquad (2^2)^2\cdot 11 \end{cases}\implies \sqrt{2^2\cdot 7}\cdot \sqrt{(2^2)^2\cdot 11} \\\\\\ 2\sqrt{7}\cdot 2^2\sqrt{11}\implies 2\sqrt{7}\cdot 4\sqrt{11}\implies 8\sqrt{7\cdot 11}\implies 8\sqrt{77}

I need help with this please
Nookie1986 [14]

Answer:

steps below

Step-by-step explanation:

3.2.1   AD = DB* sin 2 = DB * sin θ   .. DE // AB   ∠2= θ  ... (1)

By laws of sines:  DB / sin ∠5 = x / sin ∠4    

∠4 = θ-α     ∠5 = 180°-<u>∠1</u>-∠4 = 180°-<u>∠3</u>-∠4 = 180°-(90°-θ)-(θ-α)) = 90°+α

DB = (x*sin ∠5)/sin (θ-α)

     = (x* sin (90°+α)) / sin (θ-α)

AD = DB*sinθ

     = (x* sin (90°+α))*sinθ / sin (θ-α)

     = x* (sin90°cosα+cos90°sinα)*sinθ / sin (θ-α)    .... sin90°=1, cos90°=0

     = x* cosα* sinθ / sin (θ-α)

3.2.2 Please apply Laws of sines to calculate the length
