As shown below, an observer (O) is located 660 feet from a tree (T). The observer notices a hawk (H) flying at a 35° angle of elevation from his line of sight. What equation and trigonometric function can be used to solve for the height (h) of the hawk? What is the height of the hawk? You must show all work and calculations to receive full credit.

Best ResponseYou've already chosen the best response.1Yes this is a right triangle. It looks like a right triangle and I will assume the tree grow straight lol.

Best ResponseYou've already chosen the best response.1One of the trig function can be applied here. The question is which one.

Best ResponseYou've already chosen the best response.1\[ \sin(\theta)=\frac{\text{opposite}}{\text{hypotenuse}}\\ \cos(\theta)=\frac{\text{adjacent}}{\text{hypotenuse}}\\ \tan(\theta)=\frac{\text{opposite}}{\text{adjacent}} \]

Best ResponseYou've already chosen the best response.1Hypotenuse is independent of which angle you choose. Adjacent and opposite however do. Note that you cannot choose the right angle to use the trig functions.

Best ResponseYou've already chosen the best response.1Hypotenuse is the side that is longest and is opposite to the right angle. Using the opposite to right angle definition is safer since in exams those teachers could trick you and draw a triangle not to scale.

Best ResponseYou've already chosen the best response.0so the function is sin? @thomas5267

shesolitt

Best ResponseYou've already chosen the best response.0because it says hypotenuse over opposite

Best ResponseYou've already chosen the best response.0so how would i find the hawk do i use the distance formula

shesolitt

Best ResponseYou've already chosen the best response.0for the height of the hawk

Best ResponseYou've already chosen the best response.1\[\tan(\theta)\] Any ideas?

Best ResponseYou've already chosen the best response.0no ): still.. @thomas5267

thomas5267

Best ResponseYou've already chosen the best response.1\[ \tan(\theta)=\frac{\text{opposite}}{\text{adjacent}}\\ (\text{adjacent})\tan(\theta)=\frac{\text{opposite}}{\text{adjacent}}\text{adjacent}\\ (\text{adjacent})\tan(\theta)=\text{opposite} \]

shesolitt

Best ResponseYou've already chosen the best response.0so the function would be tan

Best ResponseYou've already chosen the best response.0how do i write an equation @thomas5267

thomas5267

Best ResponseYou've already chosen the best response.1\[ \theta=35\deg\\ \text{adjacent}=660\text{ ft} \] All given in the picture.

Best ResponseYou've already chosen the best response.0yes that helps lol thanks

Best ResponseYou've already chosen the best response.0so for the height i divide 660/35 @thomas5267

thomas5267

Best ResponseYou've already chosen the best response.1You want \(660\tan(35\deg)\).

Best ResponseYou've already chosen the best response.0so....an(35)=h660 h=660×tan(35) then i calculate the value of h @thomas5267

Best ResponseYou've already chosen the best response.0thank youuuuu lol i get it now !. so thats all i should write? @thomas5267

thomas5267

Best ResponseYou've already chosen the best response.1Yep. You can get \(\tan(35\deg)\) using calculator. Make sure the calculator is using degree mode.

Best ResponseYou've already chosen the best response.0i got 0.7 @thomas5267

Best ResponseYou've already chosen the best response.0thats my final answer @thomas5267

thomas5267

Best ResponseYou've already chosen the best response.1Yes, but why do you need to state the complementary angle? It is not ask in the question right? \[ \tan(35\deg)=0.7020754 \]
