Answer:
Jim is 12.87 meters away from the shark.
Step-by-step explanation:
We are given that,
Distance between Jim and Tara = 20 meters.
The angle of depression of the shark from Jim and Tara is 47° and 40° respectively as shown in the figure below.
So, the third angle of the triangle formed is given by,
47° + 40° + ∠S = 180°
i.e. ∠S = 180° - 87°
i.e. ∠S =93°
So, now using the sine ratio formula, we have,
i.e. 
i.e. 
i.e. x = 12.87 meters
Thus, Jim is 12.87 meters away from the shark.
Answer:
The temprature change was +190 degrees farenheit
Step-by-step explanation:
subtract 290-100 using absolute value
Answer:
Step-by-step explanation:
x = 61⁰
Reason: x + 29⁰ = 90⁰ ( right angles i.e the angles are perpendicular to one another)
x = 90⁰ - 29⁰
x = 61⁰
Answer:
$156.86
Step-by-step explanation:
To calculate tip, you need to multiply the total bill by the percent tip you are going to leave. In this case the bill is $136.40, and the customer is going to leave a 15% tip. So, you would want to move the decimal place over to the left by 1, which you should get 13.64 as your number. Then divide it in half, which should give you 6.82. Now add 13.64 and 6.82 with the original bill price. If you don't add the 13.64 you would've forgotten the 10% part of the tip. At the end you should get $156.86 as your final bill.
