Maurinko [17]

Answer:

X = 33,669.78 ft

Y = 15285.76 ft

Step-by-step explanation:

Given data:

let x be the distance btwn arch and plane

and y be the distance btwn ground point and arch y

we know that

$cos\theta = \frac{adjacent}{hypotaneous}$

$cos(27) = \frac{30,000}{x}$

xcos27 = 30000

$x = \frac{30000}{cos 27}$

x = 33,669.78 ft

b) we knwo that

$tan \theta = \frac{opposite}{adjacent}$

$tan 27 = \frac{y}{30000}$

y = tan(27) (30000)

y = 15285.76 ft

Find the number n that fits all of these conditions.
