Question

sin theta = 1/9 and cot theta= 36/13
what is cos theta

Answer 1

sin is opposite/hypotenuse

cot is adjacent/opposite

cos is adjacent/ hypotenuse

Answer 2

ring a bell?

Answer 3

Sin=opp/hyp.
Cos=adj/hyp

Answer 4

Draw a triangle with your values. Theta is your angles and you have opposite and adjacent values.

Answer 5

cos theta = 36/9?

Answer 6

yes!!

Answer 7

do you have to simplify?

Answer 8

cot = 36/13? is it really over 13?

Answer 9

Draw a triangle with your values. Theta is your angles and you have opposite and adjacent values.

Answer 10

yea

Answer 11

then you have to make 1/9 have a numerator of 13

sin = 13/117

therefore hypotenuse is 117

Answer 12

therefore it isnt 36/9 sorry...

Answer 13

36/117 then, so why isn't it 36/9?

Answer 14

because it says in cot that 36/13 therefore 13 should be the opposite

but in sin it says that sin = opposite/hypotenuse = 1/9 therefore we turn the opposite into 13

Answer 15

ooo ok so is cos 36/117 then
