The picture below shows a box sliding down a ramp: A right triangle ABC has measure of angle ABC equal to 90 degrees and measure of angle ACB equal to 68 degrees. The length of AB is 14 feet. What is the distance, in feet, that the box has to travel to move from point A to point C? 14 sin 68° 14 cosec 68° 14 divided by sec 68 degrees 14 divided by cot 68 degrees

sin 68 = 14 / AC
anonymous
  • anonymous
so would it be the first option then?

There might be a typo in your choices The correct answer is not there

Are you sure? there isn't an answer there that is even remotely close to the real answer?
welshfella
  • welshfella
sin 68 = 14 / AC cross multiply AC * sin 68 = 14 divide both sides by sin 68 AC = 14 / sin 68
anonymous
  • anonymous
what about 14 / sec 68?
welshfella
  • welshfella
maybe sec in option C should be sin
anonymous
  • anonymous
yes maybe, anyways thanks for the help!

Two boats start their journey from the same point A and travel along directions AC and AD, as shown below: ABC is a right triangle with measure of angle ABC equal to 90 degrees and length of AB equal to 400 feet. There is a point C on BD such that measure of angle ACB is 60 degrees and measure of angle ADC is 30 degrees. What is the distance, CD, between the boats?

oh hold 1/sin = cosec so its B 14 cosec 68
welshfella
  • welshfella
First question answer is B
anonymous
  • anonymous
oh alrightt thanks
anonymous
  • anonymous
But please help me on this question as well, i dont have alot of time and need to be done with two more questions including the one i just sent!

Find length of BD from the big triangle ABD using tan 30 = 400 / BD then find length of BC from the small triangle using tan 60 = 400 / BC then CD = BD - BC
anonymous
  • anonymous
when i do tan 30 i get .5
anonymous
  • anonymous
and tan 60 is 1.7
anonymous
  • anonymous
Would you mind just giving me the answer? I know it's the right thing to do, but i'll learn it soon enough I think and i have to go in like 10 minutes
anonymous
  • anonymous
it's not the right thing to do**
welshfella
  • welshfella
tan 30 = 0.5774 and tan 60 = 1.7321
welshfella
  • welshfella
BC = 400 / 1.7321 and BD = 400 / 0.5774
anonymous
  • anonymous
BC= 230.933
welshfella
  • welshfella
work those 2 out then DC = BD - BC
anonymous
  • anonymous
BD= 692.761
welshfella
  • welshfella
right
anonymous
  • anonymous
DC=461.828
anonymous
  • anonymous
thank you so much!
anonymous
  • anonymous
One final question please!!
welshfella
  • welshfella
that right yw
