Answer:
![\cos\theta=\frac{10}{\sqrt{116}}](https://tex.z-dn.net/?f=%5Ccos%5Ctheta%3D%5Cfrac%7B10%7D%7B%5Csqrt%7B116%7D%7D)
Step-by-step explanation:
To solve this, we can imagine a line drawn directly down from the point (10,4) to the x-axis. This would make a right triangle with length 10 and height 4.
is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.
We can use Pythagorean's Theorem to find the hypotenuse (let
represent the length of the hypotenuse):
![10^2+4^2=c^2](https://tex.z-dn.net/?f=10%5E2%2B4%5E2%3Dc%5E2)
![100+16=c^2](https://tex.z-dn.net/?f=100%2B16%3Dc%5E2)
![116=c^2](https://tex.z-dn.net/?f=116%3Dc%5E2)
![c=\sqrt{116}](https://tex.z-dn.net/?f=c%3D%5Csqrt%7B116%7D)
Thus, we know the adjacent is 10, and the hypotenuse is
. This means
.
