I think it D cause 30(cos(30x)+14=-16
Your dividing by 30
your 180 (which is degrees) is
radians. As the cosine function is periodic with period 2 we get

Find the distance between the points (-1,-2) and (5,2). Simplified radical form.

frozen [14]

Answer:

2 $\sqrt{13}$

Step-by-step explanation:

Using the distance formula,

$\sqrt{( x_{2}-x_{1} )^2+(y_{2} -y_{1})^2 }$

We just need to plug in the numbers.

So $\sqrt{(-1-5)^2+(-2-2)^2}$

Then we simplify it to

$\sqrt{(-6)^2+(-4)^2} , to \sqrt{36+16}$

Finally, we get

$\sqrt{52}$ , which is $2\sqrt{13}$ when simplified.

Need help with this trigonometry word problem

creativ13 [48]

The distance between the tree and the tower is 30√3m.

Justification:

<u>Let the situation be in a right angleABC form as shown in attached figure</u>.

<u>Given the height of the tower is 30m and the angle of depression to the base of the tree measure 30°</u>.

So, In ΔABC

tanθ = p/b

tan30° = 30/BC

1/√3 = 30/BC

BC = 30√3m.

Please help!!! Please hellp me i do not know the answr to this question.

Alchen [17]

Answer:

77.7

Step-by-step explanation:

First all the angles add up to 360°. You would subtract 180 from the 360 because of the 2 right angles. That leaves you with 180. Then 180-102.3 to get 77.7°, your answer.
