Answer:
The distance of helicopter from the injured person is 542.82 feet
Step-by-step explanation:
Given as :
The height of the hovering helicopter above the ground = h = 450 feet
The angle of elevation from injured person to helicopter = Ф = 56°
Or, Let the distance of of helicopter from person = x feet
Now, From Triangle
∵ Sin Ф = 
∴ Sin 56° = 
Or, 0.8290 = 
Or , x = 
I.e x = 542.82 feet
So, The distance from injured person to helicopter = 542.82 feet
Hence The distance of helicopter from the injured person is 542.82 feet Answer
Answer:
To reduce a fraction: divide the numerator and denominator by their greatest common factor, GCF.
Fraction: 9/10 already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
9 = 32;
10 = 2 × 5;
gcf (32; 2 × 5) = 1;
Fraction: - 3/4 already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
3 is a prime number;
4 = 22;
gcf (3; 22) = 1;
LCM (10; 4) = 22 × 5 = 20
3/20 is the answer.........
