$(a+b)(c+d)=ac+ad+bc+bd\\\\(x+8)(x+3)=x\cdot x+3\cdot x+8\cdot x+8\cdot3\\\\=x^2+3x+8x+24=x^2+11x+24$

Multiply everything in first bracket with the wats in the second so x*x = x^2 and x*3= 3x and 8*x=8x and 8*3= 24.

Answer:

In the figure below :

d = 2.08, e = 5, c = 5.42 , a = 22.78°, b = 67.22°

Step-by-step explanation:

Side lengths :

$2\cdot e=10\\ \Rightarrow e=5 feet\\\frac{d}{e}=\frac{5}{12}\\\Rightarrow d=\frac{25}{12}\approx 2.08 feet$

By pythagoras theorem,

$c^2=d^2+e^2\\c^2=29.33\\c\approx 5.42 feet$

Now to find angles,

$a+b+90^{\circ}=180^{\circ}\\\Rightarrow a+b=90^{\circ}\\\tan a=\frac{d}{e}\\\Rightarrow \tan a =0.42\\\Rightarrow a=22.78^{\circ}\\\Rightarrow b=67.22^{\circ}$
