Best ResponseYou've already chosen the best response.0You have 2 angles. You know that the sum of the angles of a triangle are =180 so what is the measure of the unknown angle Z

Best ResponseYou've already chosen the best response.0Okay So for this we're going to use 50degrees, x and 35

Best ResponseYou've already chosen the best response.0wait 50 degrees? you mean 48?

Best ResponseYou've already chosen the best response.0x is opposite 52 degrees and 35 is adjacent 52 degrees, got that much?

Best ResponseYou've already chosen the best response.0So which trig function deals with opposite and adjacent?

cutiecomittee123

Best ResponseYou've already chosen the best response.0so tan(52)=x/35

Best ResponseYou've already chosen the best response.0yes And to get x by itself what do you have to do?

cutiecomittee123

Best ResponseYou've already chosen the best response.0multiply each side by 35 and so 35tan(52)=x

Best ResponseYou've already chosen the best response.0Are you expected to have a numerical answer, and if so do you have access to a graphing calculator to solve that?

Best ResponseYou've already chosen the best response.0and on my calculator i get 44.79795713 so i rounded it to 44.80 is that right?

Best ResponseYou've already chosen the best response.0this time solve for z. cant i just add together the given angles sp 90+47 and then subtract that from 180?

cutiecomittee123

Best ResponseYou've already chosen the best response.0so then z=43 degrees

anonymous

Best ResponseYou've already chosen the best response.0Yes because you know the triangle is =180 and the 90deg angle is given aswell as 47

anonymous

Best ResponseYou've already chosen the best response.0Yes, 1809047=43 :)

Best ResponseYou've already chosen the best response.0Well the question is: A lamp casts a shadow of a man standing ten feet away from the lamp post the shadow is 7 feet long the angle of elevation from the tip of the shadow of the lamp is 50 degrees. To the nearest foot the lampost is how tall?

Best ResponseYou've already chosen the best response.0tan(50)=man/7 man=7tan(50) and man= how tall he is .

anonymous

Best ResponseYou've already chosen the best response.0Throw that in a calculator and see if it matches with an answer

cutiecomittee123

Best ResponseYou've already chosen the best response.0wait so it would be tan(50)=x/7 multiply both sides by 7 and then 7tan(50)=x right?

anonymous

Best ResponseYou've already chosen the best response.0Think so, I belive that makes him 8.3~ feet tall

cutiecomittee123

Best ResponseYou've already chosen the best response.0wow so x=8.34 feet that a tall man!

Best ResponseYou've already chosen the best response.0oh we are finding the height of the lamp post! much better lol. I am doing a test but it is open notes and I had things similar on my notes but i always like to check and make sure i am doing it right ya know?

anonymous

Best ResponseYou've already chosen the best response.0Can you change your answer, ior retake it as a whole

cutiecomittee123

Best ResponseYou've already chosen the best response.0but that would make more sense because ou have to keep in mind the shadow of the man also adds into the horizontal length
