Using Pythagorean theorem, we can find that DG is 10.(I don't think I need to explain this)

Now cosD means the adjacent side over the hypotenuse.

The side adjacent to <D is 6 and the hypotenuse is 10 so

cosD=6/10=3/5

Which means the correct answer is choice D.

Hope this helped!

Which of these strategies would eliminate a variable in the system of equations? \begin{cases} 6x + 5y = 1 \\\\ 6x - 5y = 7 \end
frez [133]

Answer:

Option A and B are correct

Step-by-step explanation:

We have to add here

6x+5y=1.

6x-5y=7

sow e will get 12x=8 , x=8/12=2/3

Option A  is correct.

If We substract bottom from furst then

6x+5y=1

-6x+5y=-7

10y=-6

y=-6/10=-3/5

we put y=-3/5 in any equation and find x

6x+5(-3/5)=1

6x=4

x=4/6=2/3

So Option B also correct.
