Answer: 84.1m

Step-by-step explanation:

Let the height of the flagpole be represented by x.

First and foremost, we have to know that the cosine of 18° = 0.9511.

The equation to get the height will then be:

0.9511 = 80/x

Cross multiply

(0.9511 × x) = 80

0.9511x = 80

Divide both side by 0.9511

0.9511x/0.9511 = 80/0.9511

x = 84.1

The height of the flagpole is 84.1m

What is the value of x, the side length of the smallest square (please show work) Thanks!
Ratling [72]

Answer:

8 cm

Step-by-step explanation:

Ok lets on the biggest square we have 17 cm

17cm is the hypotenuse for the right triangle

The second largest's area is 225 cm^2

Sq root of 225 cm^2, is 15

To find x, lets plug the info we have to the pythagorean theorom

a^2 + b^2 = c^2\\a^2 + 15^2 = 17^2\\a^2 + 225 = 289\\\\289 - 225 = a^2\\64=a^2\\a = 8 cm

The side length of the smallest Square is 8 cm

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

I don’t understand the question
If you mean
7m-4
M=8, this is the solution
7(8)-4
56-4
=52
But if you mean
7m- - 4
As in - + - = +
Then this is your answer
7(8)+4
56+4
=60
