Question

Television sizes are based on the length of the diagonal of the television's rectangular screen. So, for example, a 70-inch television is a television having a diagonal screen length of 70 inches. If a 70 inch television's diagonal forms a 29° angle with the base of the screen, what is the vertical height (h) of the screen to the nearest inch

Answer 1

You can use trigonometry to get the value

Answer 2

Have you heard of sin, cos tan, and so on?

Answer 3

yes

Answer 4

what about SOHCATOA

Answer 5

yes

Answer 6

i just don't know what to do on this one

Answer 7

Since we are looking for the vertical height, which we can assume to be v, \[\sin 29=\frac{ v }{ 70 }\]

Answer 8

I don't know what to do after that

Answer 9

Using a calculator sin29 is -0.66363388421

Answer 10

yes i got that

Answer 11

which is 46 to the nearest inch

Answer 12

why do you X by 7

Answer 13

Sorry that is supposed to be 70

Answer 14

that's ok

Answer 15

do you get it now

Answer 16

kind of just what do you mean by 46

Answer 17

I approximated that long decimal 46.45437... to the nearest inch which is a whole number that is 46

Answer 18

would you like to see the answers they gave me

Answer 19

yep

Answer 20

is -46 or -70 among them

Answer 21

1.7
1.8
13.7
14.6

Answer 22

wow i'm not really sure about those options because the question says to the nearest inch

Answer 23

That's what I was thinking

Answer 24

can you see if you can do another one unless the whole lesson is messed up

Answer 25

ok
