The angle of depression is the angle that is created from a horizontal line drawn from the upper angle of the right triangle that is created in this situation. The angle of depression is an angle exterior to the triangle. It is complementary to the interior angle. So if the angle of depression is 30 and lie outside the triangle, the interior angle has to measure 60. The pole creates a 90 angle with the ground, so what we have here is a 30-60-90 triangle. The one base angle is the right angle (the one the pole makes with the ground) and the other base angle measures 30. We are given the length of the base leg as 75 and we are looking for the height of the pole (the other leg). You would use the tangent ratio to solve for the height of the pole.
Tan(30)=x/75, and 75 tan(30)=x. Doing that on your calculator in degree mode gives you a pole height of 43.3 feet, or 43 feet (which is the height to the nearest foot)
Answer:
B
Step-by-step explanation:
The tangent- chord angle is calculated as
∠ABC = 0.5( m arc AXB) = 0.5 × 196° = 98° → B
Answer:
Basically if your spending like 10 minutes trying to understand that hand writing the question is asking for the formula you would use to find the distance and the ANSWER is <u><em>√(32-18)^2+(16-20)^2</em></u>
Step-by-step explanation:
Which im a very stubborn person and i tried to solve that language from NBG1 and it click, if you replace the variables from the Distance Formula then you will get the answer
But if you are trying to solve the distance then it will be <em><u>18.4</u></em> because you find the distance from the 3rd missing dot which will be( 18,16) and you will get <u><em>√(</em></u>4^2+18^18)
which will give you <u><em>√</em></u>340
<u><em>and you have to estimate to the nearest tenths which will be 18.4 </em></u>
So the exchange rate from one US dollar to a Canadian dollar is equal to 1.30 Canadian dollars. So in this current situation if you swapped all of your US dollars for Canadian dollars you would have $13000 Canadian dollars
