Answer:
9.17 feet.
Step-by-step explanation:
See the diagram attached to this answer.
Let, AB is the pole and CD is the tree.
From the top of the pole to the base of the tree the angle of depression as per the condition is 63°.
So, ∠ EBC = ∠ ACB = 63° {Since, BE ║ AC}
So, from Δ ABC, 
{Given height of the tower AB = 18 feet}
⇒ 
feet.
Therefore, the distance between the pole and the tree is 9.17 feet. (Answer)
Answer:
x=1, x=7
Step-by-step explanation:
Firstly, you can simplify by dividing both sides by 3, which will make the equation easier to simplify:
(x-4)^2=9
Next, you can take the square root of each side, which will cancel the square, and make the 9 even easier to work with:
(x-4)=(±
)3
*Note the (±
) sign, this is because there is a positive and negative answer*
After this, you will basically have two equations:
(x-4)=3
and
(x-4)=-3
You are going to solve both to get both answers, but lets start with the positive first:
x-4=3 Add 4 to both sides to get an x= equation
<u>x=7</u>
And it's the same thing for the negative:
x-4=-3 Add 4 to both sides to get an x= equation
<u>x=1</u>
Hope this helps
Answer:
The answer is 50
Step-by-step explanation:
= -3(-2-3×6)-5{4+2(-1)}
= -3(-2-18)-5{4-2}
= -3(-20)-5{2}
= 60-10
= 50
Answer:
Here's how to solve
Step-by-step explanation:
Okay so 13 -5
What can you add to 5 to get 13?
5+5=10
5+6=11
5+7=12
5+8=13
8 would be your answer.
Answer:
10c ≥ 150
At least 15 cars (or c ≥ 15)
Step-by-step explanation:
If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.
This equation can be used to express the situation:
10c ≥ 150
<em>To solve you divide the 10 from both sides of the inequality to get.</em>
c ≥ 15
