the best answer gets brainiest! <3 What is p ÷ r equal to?

tan x°
tan y°
sin y°
cos x°

sorry for sloppy typing

Step-by-step explanation:

Answer

Making use of given relations , we have

cos 2x=tan 2 y=sec 2 y−1=cot 2 z−1or 1+cos 2x= 1−cos 2 z cos 2 z= 1−tan 2 xtan 2 x or1+cos 2 x= cos 2 x−sin 2 x sin 2 x

On changing to sin x, we get,

(2−sin 2 x)(1−2−sin 2 x)=sin 2 xor2sin 4

x−6sin 2x+2=0 orsin 4 x−3sin 2x+1=0∴sin 2x= 23± 9−4= 23±5 =23− 5

We have reject the value 23+ 5 as it is >1 or sin 2 x= 46−25 =( 25 −1 ) 2∴sinx= 25 −1 =2. 45−1 =2=sin18∘

By Symmetry we can say that,

sin x = sin y = sin z = 2sin18 ∘

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

f(x) = y

f(-3) = -5
