Answer 1

you can use the trig identity

Answer 2

better we represent it to figure :

Answer 3

to find cot, u have to determine the value of x

Answer 4

use pythagorean theorem :
x^2 = 7^2 - 1^2
solve for x

Answer 5

after u got the value of x, then evaluate the cot :
cot(theta) = x/1 = ....
it must be positive value, because theta in quadrant 3

Answer 6

\[\cot^2(\theta)=\csc^2(\theta)-1\]

Answer 7

that will work too..
upto u which way do u want, @minabina678 ::)

Answer 8

the final answer will be same

Answer 9

umm this what i did

Answer 10

-7²=cot²theta+1
-49-1=cot²theta-1
√-50= √cot²
