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
i saw your post @wel
sin 68 = 14 / AC
so would it be the first option then?
There might be a typo in your choices The correct answer is not there
14 sin 68° 14 cosec 68° 14 divided by sec 68 degrees 14 divided by cot 68 degrees
What is the distance, in feet, that the box has to travel to move from point A to point C?
Are you sure? there isn't an answer there that is even remotely close to the real answer?
sin 68 = 14 / AC cross multiply AC * sin 68 = 14 divide both sides by sin 68 AC = 14 / sin 68
what about 14 / sec 68?
maybe sec in option C should be sin
yes maybe, anyways thanks for the help!
can you answer another question for me?
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
First question answer is B
oh alrightt thanks
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
when i do tan 30 i get .5
and tan 60 is 1.7
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
it's not the right thing to do**
tan 30 = 0.5774 and tan 60 = 1.7321
BC = 400 / 1.7321 and BD = 400 / 0.5774
work those 2 out then DC = BD - BC
thank you so much!
One final question please!!
that right yw
