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:
15-6x= -12-4x
15-2x= -12
-2x= -27
x= -13.5
Step-by-step explanation:
x-intercept means f(x) = 0
(x-8)(x+9) = 0 ⇒ x = 8 or x = - 9
There are two points which are x-intercepts. They are (8,0) and (-9,0).
Answer:
C
Step-by-step explanation:
If you would like to know if is 5/12 greater than 0.44, you can calculate this using the following step:
0.44 = 44/100 = 11/25 = 132/300
5/12 = 125/300
Result: 0.44 is greater than 5/12 (0.44 = 132/300 > 5/12 = 125/300).
