Answer:
?
Step-by-step explanation:
D because its more formal then the other ones.
3x5 = 15, 15^2 = 225.
3^2 = 9 and 5 x + = 45.
225-45 = 180. hope this helps :)
So sin in math means:
In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. The abbreviation is sin.
Con in math means:
In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse.
in this case it has to be a sin. So its either A, or B.

To answer this question you need to understand the relationship between the hypotenuse and the 2 other sides of a right triangle. We use The pythagorean theorem to help us see the relationship. 3^2+4^2=c^2, so 25=c^2. C=5.
You will use the lines to show 3 and 4 and the hypotenuse is the slanted side. See picture.
