Answer 1

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

Answer 2

i saw your post @wel

Answer 3

@welshfella

Answer 4

sin 68 = 14 / AC

Answer 5

so would it be the first option then?

Answer 6

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

Answer 7

14 sin 68°
14 cosec 68°
14 divided by sec 68 degrees
14 divided by cot 68 degrees

Answer 8

What is the distance, in feet, that the box has to travel to move from point A to point C?

Answer 9

Are you sure? there isn't an answer there that is even remotely close to the real answer?

Answer 10

sin 68 = 14 / AC
cross multiply
AC * sin 68 = 14
divide both sides by sin 68
AC = 14 / sin 68

Answer 11

what about 14 / sec 68?

Answer 12

maybe sec in option C should be sin

Answer 13

yes maybe, anyways thanks for the help!

Answer 14

Answer 15

can you answer another question for me?

Answer 16

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?

Answer 17

oh hold 1/sin = cosec

so its B 14 cosec 68

Answer 18

First question answer is B

Answer 19

oh alrightt thanks

Answer 20

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!

Answer 21

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

Answer 22

when i do tan 30 i get .5

Answer 23

and tan 60 is 1.7

Answer 24

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

Answer 25

it's not the right thing to do**

Answer 26

tan 30 = 0.5774
and tan 60 = 1.7321

Answer 27

BC = 400 / 1.7321
and BD = 400 / 0.5774

Answer 28

BC= 230.933

Answer 29

work those 2 out then DC = BD - BC

Answer 30

BD= 692.761

Answer 31

right

Answer 32

DC=461.828

Answer 33

thank you so much!

Answer 34

One final question please!!

Answer 35

that right
