Answer:the sailboats are 358 feet apart.
Step-by-step explanation:
The diagram of the triangle representing the situation is shown in the attached photo.
B represents the position of the lighthouse.
D represents the position of the first sailboat.
C represents the position of the second sailboat.
x represents the distance between the two sailboats
We would apply trigonometric ratio
Tan # = opposite/adjacent
For triangle ABD,
Tan 12 = 370/AD
AD = 370/Tan 12 = 370/0.2126 = 1740.357 feet
For triangle ABC,
Tan 10 = 370/AC
AD = 370/Tan 10 = 370/0.1763 = 2098.695 feet
x = AC - AD = 2098.695 - 1740.357 = 358 feet
Answer: -170
Concept:
When encountering questions that require multiple steps of the calculation, it is suggested to follow the PEMDAS.
- <u>P</u>arenthesis
- <u>E</u>xponents
- <u>M</u>ultiplication
- <u>D</u>ivision
- <u>A</u>ddition
- <u>S</u>ubtraction
Solve:
**Disclaimer** I assume that it is supposed to be (25 + 45). If it was, then you may refer to my answer. If the ")" after 45 is just a typo, you may point it out and I will redo it.
<u>Given expression</u>
13 + {16 + 2 - [(25 + 45) × 3] + 9}
<u>Do the parenthesis of the inner most</u>
=13 + {16 + 2 - [70 × 3] + 9}
=13 + {16 + 2 - 210 + 9}
<u>Do addition first, then subtraction</u>
=13 + {18 - 210 + 9}
=13 + {27 - 210}
=13 - 183
=-170
Hope this helps!! :)

Answer:
Since there is only 1/5 that is the amounts of fives so it would be 1/5 divided = 0.2 times 3 = 0.6 so 0.6 is the answer
I’m really sorry if I’m wrong ...
Answer:
yes yes no no
Step-by-step explanation:
use the Pythagorean theorem. sub a^2+b^2=c^2.
c is the largest number, and you can plug the 2 other values into a and b.
