sin= \frac{opp}{hyp} \\\\sin (20) = \frac{10000}{hyp}\\\\hyp= \frac{10000}{sin(20)} \\\\hyp= 29238 ft

The aircraft is 29238 ft from the ship

Note: this is based on my assumption that we are looking for the hypotenuse.

Solve 4(4f-9)=-(2-f)
Whitepunk [10]

Answer:

f = \frac{7}{15}

Step-by-step explanation:

1. 4(4f - 9) = -(2-f)               distribute the negative

2. 4(4f - 9) = -2 + f           Distribute the 4

3. 16f - 9 = -2 + f            Subtract f on both sides

4. 15f - 9 = -2                  Add 9 on both sides

5. 15f = 7                 Divide both equations by 15

6. \frac{15f}{15} = \frac{7}{15}  

f = \frac{7}{15}
