Answer:

Step-by-step explanation:

Remark

There are a couple of ways that would produce the right answer. The proportion must be set up so that likes are on the numerator and denominator.

6.5 vertical height of the small triangle/ horizontal small 10 =

x vertical of the tree/ 40 horizontal of the tree.

Notice what we have

vertical / horizontal = vertical / horizontal

6.5 / 10 = x / 40 Cross multiply

6.5 * 40 = 10 * x

260 = 10 * x Divide by 10

26 = x

Haylee hikes to the top of a 120-foot vertical cliff. From the top of the cliff, the angle of depression to her campsite is 10∘.

stiv31 [10]

Answer:

681 feet

Step-by-step explanation:

Let x represent the distance between campsite and the base of the cliff.

We have been given that Haylee hikes to the top of a 120-foot vertical cliff. From the top of the cliff, the angle of depression to her campsite is 10∘. We are asked to find the distance between campsite and the base of the cliff.

We can see that angle of depression forms a right triangle with respect to ground, cliff and campsite.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

$\text{tan}(10^{\circ})=\frac{120}{x}$

$x=\frac{120}{\text{tan}(10^{\circ})}$

$x=\frac{120}{0.176326980708}$

$x=680.5538183559$

Upon rounding to nearest foot, we will get:

$x\approx 681$

Therefore, the campsite is 681 feet away from the base of the cliff.

Does 1.414213562 round to the nearest tenth.

WITCHER [35]

Hey there!

Yes, it does. It rounds to 1.4.

1.414213562 rounded to the nearest tenth is 1.4, since the next number is less than 5, the 4 stays the same. If the next number was a 5 or greater, it would be 1.5, instead of 1.4.

Hope this helps! Good luck and have great day!

What's the correct answer for this?<br><br>please help me out!!

natima [27]

X=25 is the answer

EXPLANATION:

Since we have here similar triangles, then 2x+2/x+3 must be equivalent of 26/14

2x+2/x+3=26/14
2x+2/x+3=13/7
7(2x+2)=13(x+3)
14x+14=13x+39
x=25
