Answer:
42.1 degrees
Step-by-step explanation:
- since we have a opposite/hypotenuse ratio, that means we used sin x = o/h
- this means, sin x = 0.67
so, x = 
(0.67) {sin inverse}
x = 42.06 degrees, i rounded it up to 42.1 but its up to you (or according to the question)
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:
x = 5
Step-by-step explanation:
3x-1 = 5x-11
<em>Subtract 3x from both sides:</em>
-1 = 2x - 11
<em>Add 11 to both sides:</em>
10 = 2x
<em>Divide both sides by 2:</em>
5 = x
Answer:D. The atmosphere of Mars is twice as thick as scientists predicted it would be.
Step-by-step explanation:
Many fractions are equal. You can double both numbers to make a new fraction with the same properties, or times them both by 10 or more.
Examples of answers:
10/16
50/80
500/800 etc...
