Find cosØ if sinØ=-12/13 and tanØ>0. A) -5/12 B) -5/13 C) 12/5 D) -13/12

mestny [16]

Answer:

-5/13

Step-by-step explanation:

sin theta = opp / hyp

sin theta = -12 /13

we can find the adj side by using the pythagorean theorem

adj^2 + opp ^2 = hyp^2

adj^2 +(-12)^2 = 13^2

adj^2 +144 =169

adj^2 = 169-144

adj^2 = 25

Taking the square root of each side

adj = ±5

We know that it has to be negative since it is in the third quad

adj = -5

cos theta = adj / hyp

cos theta = -5/13

(2,1),(-3,1) how do you solve this I’m looking for the slope I also have to show work

shutvik [7]

Answer: 0

Step-by-step explanation:

To find the slope, you would need to use the formula $m=\frac{y_2-y_1}{x_2-x_1}$ .

$m=\frac{1-1}{-3-2} =\frac{0}{-5} =0$

The slope is 0, meaning the line is horizontal.
