Answer:

D. 191

Step-by-step explanation:

To calculate this you need to imagine triangle which points are:

boat

Top of lighthouse

Bottom of lighthouse

That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse

tan(25) = 89/x

x = 89/tan(25)

x = 190.86

after rounding, your final answer would be 191 feet.

the area of a rectangular painting is 5346cm square. if the width of the painting is 66 centimeters what is its lenght

Vanyuwa [196]

The area of a rectangle is length*width

Since we have the width, we can do 5346/66 to get the length

So the length is 81 cm

Find the length of the third side. If necessary, round your the nearest tenth.

Ksivusya [100]

Answer:

Step-by-step explanation:

Use Pythagorean theorem,

base² + altitude² = hypotenuse²

7² + altitude² = 25²

altitude² = 25² - 7²

= 625 - 49

= 576

altitude = √576

altitude = 24

Step-by-step explanation:

For the 1st picture,

The 2nd option is the answer.

Let say we have

$a_{3}$

Replace it into the recursive formula.

$a_{3} = a_{3 - 2} + (a) _{3 - 1}$

We are given a,1 and a,2 so the 3rd terms has to be

$2$

So the second option is the answer.

For the second picture, a geometric sequence is a group of terms that has the same ratio between each consecutively.

Infinite means going on forever

The fourth option is the answer.
