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 ∘

step-by-step explanation:

the answer is a

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
