Answer:

A. 3.66 feet

Step-by-step explanation:

Using trigonometry, we know that ...

BC = DC·tan(30°)

AC = DC·tan(45°)

AB = AC -BC = DC(tan(45°) -tan(30°))

AB = 5√3·(1 -√3/3) = 5(√3 -1)

AB ≈ 3.66 . . . feet

X-2/3= 6 1/3 what is the answer??????????

vichka [17]

For this case we must find the solution of the following equation:

$x- \frac {2} {3} = 6 \frac {1} {3}$

Rewriting the mixed number in the form of improper fraction we have:

$x- \frac {2} {3} = \frac {3 * 6 + 1} {3}\\x- \frac {2} {3} = \frac {19} {3}$

Add $\frac {2} {3}$ to both sides of the equation:

$x = \frac {19} {3} + \frac {2} {3}$

We add the fractions with the same denominator:

$x = \frac {19 + 2} {3}\\x = \frac {21} {3}\\x = 7$

So, the solution is $x = 7$

Answer:

$x = 7$
