Question

Someone helpp!

Answer 1

Looks as tho' you'll have to convert that 120 deg. angle into radian measure. How would you do that?

Answer 2

idk

Answer 3

On second thought, perhaps not. How many degrees in one full circle?

Answer 4

I am not positive but I believe since it is 1/3 of the circle you could do the 81*3.14=254.34/3=84.78.

Answer 5

DO you know this?

Answer 6

@brady101

Answer 7

I believe it would be 45 degrees not sure though

Answer 8

@sbuck98

Answer 9

it should be a decimal idk

Answer 10

You'll need to use the inverse tangent function, which your online calculator has.

Answer 11

Can you start from step 1?

Answer 12

the angle A would be the inverse tangent of 9/3

Answer 13

Have you used the inverse tangent function before on this online calculator?

Answer 14

no

Answer 15

inverse sine? inverse cosine?

Answer 16

71.565 is what it showed!

Answer 17

What did you type in?

Answer 18

Tan-1 (9/3)=

Answer 19

That's precisely what y ou were supposed to do.

This tells you that Angle A, measured in degrees, is 71,565 degrees. Since both the 3 and the 9 are whole numbers, you should round up this 71.565 degrees to 72 degrees.

Answer 20

Could you help with a few more?

Answer 21

I'd like to, but for me it's late and I need to hit the sack. Glad this session worked out well for you.
