Answer:

$\frac{x - 4}{x - 3}$

Step-by-step explanation:

$\frac{ {x}^{2} - 8x + 16 }{ {x}^{2} - 7x + 12}$

Lets split the numerator and denominator.

$= > \frac{ {x}^{2} - 4x - 4x + 16}{ {x}^{2} - 3x - 4x + 12}$

Lets factorise the numerator and denominator.

$= > \frac{x(x - 4) - 4(x - 4)}{x(x - 3) - 4(x - 3)}$

$= > \frac{(x - 4)(x - 4)}{(x - 3)(x - 4)}$

Cancelling x - 4 from numerator and denominator ,

$= > \frac{x - 4}{x - 3}$

Answer:

1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 = $\frac{h}{c}$

c = $\frac{h}{\text{tan}47}$

c = $\frac{4.8}{\text{tan}47}$

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° = $\frac{h}{b}$

b = $\frac{h}{\text{tan}37}$

b = $\frac{4.8}{1.0724}$

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° = $\frac{h}{a}$

a = $\frac{h}{\text{tan}27}$

a = $\frac{4.8}{0.5095}$

a = 9.42 m
