Step-by-step explanation:

comvert units into one unit

4ft 2in = 4 + 2/12 ft

3ft 4in = 3ft + 4/12ft

Know that the ratio of tan(x) = O / A

and set up proportions

$\frac{ba}{ac} = \frac{h}{rt}$

solve for h

Answer:

Step-by-step explanation:

assuming that the triangles are similar, which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.

' = feet

" = inches

h / 20' = 4'-2" / 3'-4"

just use inches for this, it's easier

h / 240" = 50" / 40"

h = 240 ( 50 / 40 )

h = 300"

h = 25'

What is the length of BC? If your answer is not an integer, leave it in simplest radical form?

nexus9112 [7]

ANSWER

$|BC|=12\sqrt{2}\: ft$

EXPLANATION

The given right triangle is an isosceles triangle because

$m \: < \: B = 45 \degree = m \: < \: C$
This implies that,

$|AB|=12ft=|AC|$

From the Pythagoras Theorem,

$|BC|^2=|AB|^2+|AC|^2$

$|BC|^2= {12}^{2} + {12}^{2}$

$|BC|^2=2 \times {12}^{2}$

$|BC| = \sqrt{ {12}^{2} \times 2 }$

$|BC|=12\sqrt{2}\: ft$
