Question

Find the value of the cotangent for 12 years ago

Answer 1

i really need help with this

Answer 2

use the Pythagorean theorem. You have the hypotenuse and the adjacent side, then find out the opposite.

\[(hypotenuse)^2 = (adjacent)^2 + (opposite)^2\]

Answer 3

ok, and then what?

Answer 4

i got that r = 36, now i need the angle

Answer 5

Remember that's r^2 = 36 so, r = 6, not 36.

From there you know that one side equals 90º. To find out the other angles remember that tan(theta) = sin/cos, in which equals to tan(theta) = 6/10. Use arctan to find out what theta equals and you'll have the angle of R.

From there you can find out what the angle of S is since a triangle equals 180º.

cotangent = cos/sin. You can solve the rest from here.

Answer 6

thank you
