Answer:
The cosine of angle C is 5/13, or approximately 0.38.
Step-by-step explanation:
To solve this problem, we must remember what the cosine of an angle represents. The cosine of an angle is equal to the ratio of the adjacent side divided by the hypotenuse.
From the diagram, we can determine that the adjacent side length is 10 and the hypotenuse is 26.
Therefore, the cosine of angle C is:
10/26 = 5/13 (simplified)

I think its B
Step-by-step explanation:
the only line that intersects the y axis is 3
Answer:
(2a,2b)
(-4a,b)
Step-by-step explanation:
for the first one
the x value of coordinate L is going to be twice the value of the x coordinate of k (a)
That being said the x value of L = 2a
The y value of L is going to be half the value of the y value of coordinate A ( 4b )
4b/2=2b so the y value of coordinate L is 2b
now we put the values as an ordered pair
The answer would be (2a,2b)
