Question

i need help please

Answer 1

When you are given degrees with minutes, use a proportion!

For instance, you have 47 minutes. So set it up like this

47/60 = x/100

cross multiply

60x = 4700
x= 4700/60

x=78.33333

Now just add that on to your degrees!

52* 47' = 52.78333*!

Then just type it into your calculator:

sin(52.78333*) <---- do not forget your degree sign!

and that will end up being .79635 RADIANS.

Answer 2

did it help you @purplemexican

Answer 3

yes thank you so much

Answer 4

@madhu.mukherjee.946 can you go through the last part?

Answer 5

which portion ?

Answer 6

from "Now just add that on to your degrees!" down please

Answer 7

yea

Answer 8

see previously we had multiplied with 100,then we got 4700

Answer 9

yes

Answer 10

so when you get the answer you divide that by 100
then you will get 0.7833 now add that with 52

Answer 11

so if i had

Answer 12

do it in the same way

Answer 13

and x=25 i divide 25/100 then multiply my answer by 79

Answer 14

not multiply sweety,add them

Answer 15

add sorry

Answer 16

79.25

Answer 17

im half asleep

Answer 18

its okay

Answer 19

would that be the final answer?

Answer 20

use the calculator

Answer 21

how do you do radian

Answer 22

you don't have a scientific calculator

Answer 23

i have a TI-nspire cx

Answer 24

okay .do you have a button called mode

Answer 25

hey@purplemexican

Answer 26

i dont see one

Answer 27

i have an fx 82

Answer 28

you will have a button of mode which will help you to change the degreed to radians

Answer 29

i have to go to settings for that and it was already in radians

Answer 30

should it be in degreed first

Answer 31

so what do you get as answer

Answer 32

1.62881

Answer 33

cos 79.25

Answer 34

cos(79+25)?

Answer 35

0.25

Answer 36

yes so 79.25

Answer 37

yea

Answer 38

oh

Answer 39

look first find the answer in degrees by your calculator
now multiply that with pi and divide that by 180

Answer 40

cos 79.25=0.186 degrees
