For an angle (theta) with the point (5, -12) on its terminating side, what is the value of cosine?

padilas [110]

we are given

(x,y)=(5,-12)

so, x=5 and y=-12

now, we can find r

$r=\sqrt{x^2+y^2}$

$r=\sqrt{5^2+(-12)^2}$

$r=13$

now, we can find cos

$cos(\theta)=\frac{x}{r}$

so, we get

$cos(\theta)=\frac{5}{13}$ ...........Answer

Think About a Plan Write an indirect proof.

Alekssandra [29.7K]

1) Either $\ell \parallel p$ or $\ell$ ∦ $p$ (only two possibilities)

2) Assume $\ell \parallel p$ (one of two possibilities)

3) $\angle 1 \cong \angle 2$ (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But $\angle 1$ is not congruent to $\angle 2$ (given)

5) So $\ell$ ∦ $p$ (only other possibility)

It costs $2.55 to make a sandwich at the local deli shop. To make a profit, the deli sells it at a price that is 140% of the cos

gulaghasi [49]

The answer is $3.57 because you must multiply 2.55 by 140 then divide that by 100 to find your answer hope this helps.
