At the bank of a river, by measurement, a = 18 ft. b = 30 ft. c = 24 ft. d = 14 ft. How long is x? How long is y? Angle --> https://media.glynlyon.com/a_matgeo_2011/5/group123.gif The answer should be to the nearest tenth or as a fraction. x = ? ft. y = ? ft.

anonymous
  • anonymous

anonymous
  • anonymous
all similar triangles have angles that 180 degrees when added to together.

now in the problem let's take this on triangle at time, let's start with first one
anonymous
  • anonymous
let's do the first triangle, in the first triangle we a right angle which is 90 degrees, now given the info from the problem we can now solve this by thinking about sin, cos , tan here.

anonymous
  • anonymous
yes sorry my connection sucks so it takes forever to reply
anonymous
  • anonymous
okay no prob. you have all you need to do this problem, notice on the choices give they refer to to the triangles listed on the picture so now what we have to is look at if we use sin,cos or tan in these cases to solve
anonymous
  • anonymous
so should i use the sine table for this problem?
anonymous
  • anonymous
yes sin would be a good choice in this case.
anonymous
  • anonymous
k i have a chart... https://media.glynlyon.com/a_matgeo_2011/5/groupi94.gif
anonymous
  • anonymous
so should i look for the tan numbers for each other numbers given
anonymous
  • anonymous
you can but in keep in mind what you are being asked for here.
anonymous
  • anonymous
do the top first triangle only, than we will worry about the bottom within this problem
anonymous
  • anonymous
i forgot about the angle.. that kinda looks like c = a * b
anonymous
  • anonymous
because we similar triangle here what do we know already about this?
anonymous
  • anonymous
the c=a times b is right
anonymous
  • anonymous
did you get it?
anonymous
  • anonymous
i hate this computer -.- yes i got it thanks :)
anonymous
  • anonymous
welcome any questions or are you fine now?
anonymous
