Trigonometry question!!

Answer 1

Which expression can be used to find the distance between the points B and C of the entrance?

Answer 2

What expression*

Answer 3

\[\tan(65)=\frac{BD}{15}\implies BD=15\tan(65)\] is a start

Answer 4

im assuming the arrow means you simplified

Answer 5

solved for \(BD\) i did not compute the number. we still need \(DC\)

Answer 6

\[\tan(25)=\frac{15}{DC}\implies DC=\frac{15}{\tan(25)}\] and them together to get your answer

Answer 7

since \(BD+DC=BC\)

Answer 8

How would I enter the trig functions into my calculator to compute them?

Answer 9

choice 1

Answer 10

choice 2

Answer 11

i can't read that

Answer 12

Top left corner of your screen :p

Answer 13

3 & 4

Answer 14

\[15\tan(65)+\frac{15}{\tan(25)}\] is the answer i believe
can't read the choices

Answer 15

none of the choices had Tan in them. They all contained Cot or Sec

Answer 16

then i guess we have to switch them
\[\cot(25)=\frac{DC}{15}\implies DC=15\cot(25)\]

Answer 17

since you don't have either hypotenuse you cannot use secant

Answer 18

\[\cot(65)=\frac{15}{BC}\implies BD=\frac{15}{\cot(65)}\]

Answer 19

So 15Cot(25) + 15/Cot(65)?

Answer 20

yes if that is a choice, i would pick that one
