Answer:
42°
Step-by-step explanation:
For this problem, it may help you to draw it out to visualize it. You want to find the angle between the stream and road. Based on the description the triangle looks like this.
/ |
Stream(27) / | Road( 20)
/__|
Fence
You know the length of the road is 20, and the stream is 27. The angle can be found by using Cos∅=a/h. Adjacent to where the road and stream meet is the road, 20, and hypotenuse is the stream, 27.
So 20/27 = .74 = Cos∅
To find the angle ∅ use inverse cosine to get 42°.
Hope that helps and let me know if I did anything incorrectly!
The first one is correct and the others I can't really see the picture is blurry
Answer:
x ≤
Step-by-step explanation:
Given
- 2 ≤
Multiply through by 6 to clear the fractions
2(x - 1) - 12 ≤ 5 - 2x ← distribute and simplify left side
2x - 2 - 12 ≤ 5 - 2x
2x - 14 ≤ 5 - 2x ( add 2x to both sides )
4x - 14 ≤ 5 ( add 14 to both sides )
4x ≤ 19 ( divide both sides by 4 )
x ≤

Answer:
None of these answers are correct.
Step-by-step explanation:
If a²+b²=c², then 7²+5²=c², then if you solve for c this equals about 8. This is none of the answers mentioned which is 8. Also, a good thing to remember is that the hypotenuse is always larger than the two side lengths. So, since the answer is 8 then it is none of the answers.
