Question

How do i do co-secant on the calculator?

A helium-filled balloon is attached to an 88 m long string. The string is tied to a hook on the ground and it makes an angle of 45° with the ground, as shown below.

What is the height of the balloon from the ground?
29.3 m
44 m
62.2 m
88 m

Answer 1

1/cos(x)

Answer 2

1 divided by cos(x)

Answer 3

you got you calculator?

Answer 4

yeah I do

Answer 5

cosecant is 1/sinx

Answer 6

what are you trying to find the cosine of ?

Answer 7

ya 1 divided by sinx

Answer 8

you should get in the habit of writng cos(x) csc(x) etc

Answer 9

I am not exactly sure how to even set the equation up so I can find the height of the balloon

Answer 10

so, you equation would be

Answer 11

\[\sin(45)=h/88\]

Answer 12

\[88\sin(45)=h\]

Answer 13

you got it?

Answer 14

yeah i think so...so my answer would be 62.22?

Answer 15

yes

Answer 16

you see the drawing and what i did?>

Answer 17

sin(x)=oppisite/hypotenuse

Answer 18

:D

Answer 19

88 being the hypotenuse

Answer 20

Yeah I got it now :) thanks!
