Question

Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only)

Answer 1

Please help

Answer 2

use the cosin low what say

cos x° = adjacent side divide hypotenuse

Answer 3

13 divided by 12?

Answer 4

We see that we know of the hypotenuse as well as the adjacent side of the angle so we would use the trig ratio of cos...

\(\Huge{\cos(x)=\frac{12}{13}}\)

To find x we would invert it...

\(\Huge{\cos^{-1}(\frac{12}{13})=x}\)

Answer 5

or you write x = arccos (12/13 = ?

Answer 6

I got 1.083 *3 is repeating*

Answer 7

Hmmmm...if you are using a calculator make sure to have it in `degree mode` not radian mode...

Answer 8

okie

Answer 9

I got the same

Answer 10

Hmmm what kind of cal are u using?

Answer 11

a scientific cal. I punched in 13 divided by 12

Answer 12

I see now. You have to press \(\Large{\cos^{-1}}\) and then type 12 divided by 13....

Answer 13
