Given sin0=6/11 and sec 0< 0 find cos0 and tan0 (picture provided)

Step-by-step explanation:

We know by definition that:

We also know that:

Then we can use these identities to solve the problem

if then

As then . Therefore we take the negative root:

Now that we know and we can find

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

a
