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!
Answer:
c
Step-by-step explanation:
each bit goes up by 8
(+8)
-15 + 8 = -7
-7 + 8 = 1
1 + 8 = 9
9 + 8 = 17
and so on..
The answer for t is 4 and the proportional relationship is 9
