Answer: OC
Step-by-step explanation: exact answer is 64.6
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


xcos27 = 30000

x = 33,669.78 ft
b) we knwo that


y = tan(27) (30000)
y = 15285.76 ft
The third set is equivalent to
2x + y = 2
2x + y = -2
clearly inconsistent.
