Question

calculate cos0.
i will insert the pic

Answer 1

Cos theta is the adjacent side over the hypotenuse, so Cos theta = (10/12)
Theta = cos^-1(5/6)

Answer 2

Simplify that, and you should be good

Answer 3

simplify?

Answer 4

i dot get ur explanation

Answer 5

Simplify means to turn the equations into numbers, a proper answer.

Answer 6

yeah ik that

Answer 7

but what are u asking me to simplify

Answer 8

and what d does this "^" stand for

Answer 9

Here's how it would look.. \(\large Cos \theta = \frac{10}{12}\), \(\large \theta = cos^{-1\frac{5}{6}}\)

Answer 10

When they said "^" they were referring to exponents :)

Answer 11

then i simplify -15/6?

Answer 12

Sort of, you'd need a calculator to do so, to take the inverse of the cos of 5/6, and make sure that you're in degrees, but yes, in essece

Answer 13

can i use google?

Answer 14

Yes

Answer 15

can u help idk how to

Answer 16

The answer to theta should be the same as the last problem we did: 33.5 degrees, or Cos theta = (5/6)

Answer 17

thanks

Answer 18

i have one more and its : calculate tan 0

Answer 19

The tan of theta = opposite(6.63) / adjacent (10)

Answer 20

Theta will still be 33.5 degrees

Answer 21

which is fraction form will be?

Answer 22

Fraction form? tan theta =(6.63/10
Or Theta = tan^-1(6.63/10)
