~Will give medal to the person who helps ~
Grace is standing 14 feet from a lighthouse and Kelly is standing 12 feet from Grace. The angle that Grace looks up to see the top of the lighthouse is 45°. The angle that Kelly looks up to see the top of the lighthouse is y°.
A.Find the height, h, of the lighthouse.
B.Find the angle, rounded to the nearest tenth of a degree, in which Kelly looks up to the top of the lighthouse.
C. To the nearest tenth of a degree, find the value of x° . In two or more sentences, explain your calculations

Best ResponseYou've already chosen the best response.0soo far I was thinking maybe I should be using Tan for A to get the value of h ~ but im a little iffy if im right

Best ResponseYou've already chosen the best response.1Height should be easy Triangle BAG is a 45 45 90 triangle so its height is 14 feet

Best ResponseYou've already chosen the best response.0yea I calculated that by using tan so did i do it right ? \[\tan 45 = h/ 14 \] right ??? thats the right equation ?

Best ResponseYou've already chosen the best response.0ok i had to multiply , them which gave me 14 in the end. it threw me off.

Best ResponseYou've already chosen the best response.1Now for part B Kelly's angle would be the arc tangent of (14/26)= the arc tangent of 0.5384615385 =28.301 degrees

Best ResponseYou've already chosen the best response.0oh so we just had to combine the distance of both, well the 14 thats the height of the light house. ohh i under stand now ~~

Best ResponseYou've already chosen the best response.1Yes, that's right (kind of a lousy problem that uses a 14 foot lighthouse  kinda small isn't it?)

Best ResponseYou've already chosen the best response.0I looked up the question for help on how to do it but they kept saying its 71 for a which is weird since its kind of impossible to get 71.

Best ResponseYou've already chosen the best response.0soo a is 14 b is 28.3 since we have to round to the nearest tenth now for c

Best ResponseYou've already chosen the best response.1They are saying height = 71? Okay for part c we know y = 28.3 The angle to the right of the 45 degree angle would be 180  45 = 135 degrees

Best ResponseYou've already chosen the best response.0then we divide by two right or ?

Best ResponseYou've already chosen the best response.1They say it should be 71? Did you type up the question exactly as it is written?

Best ResponseYou've already chosen the best response.0yea , I did and it came to open study. but they made me even more confused. they had the same model everything same question.
