Use the cosine formula

Cos(angle) = adjacent/ hypotenuse

cos(30) = x/8

Cos(30) can be written as sqrt(3)/2

Now you have :

sqrt(3)/2 = x/8

Multiply both sides by 8:

X = sqrt(3)/2 x 8

Simplify:

X = 4sqrt(3)

Troyanec [42]

Answer:

$x=29$

Step-by-step explanation:

Given equation :

$\frac{(7+2x)}{5} =13$

Making the terms of 'x' to one side and constants to the other.

$(7+2x)=13*5$

$7+2x=65$

$2x=65-7$

$2x=58$

$x=\frac{58}{2}$

$x=29$

So, the value of 'x' is 29.

On a map, the distance between two historical markers is 4.5 inches, and 2.5 inches represents 10 miles.

Morgarella [4.7K]

Answer:

The actual distance between the historical markers is 18 miles.

Step-by-step explanation:

Given : On a map, the distance between two historical markers is 4.5 inches, and 2.5 inches represents 10 miles.

To find : What is the actual distance between the historical markers?

Solution :

We have given that,

2.5 inches represents 10 miles.

i.e, 1 inch represent $\frac{10}{2.5}$ miles.

1 inch = 4 miles.

Now, The distance between two historical markers is 4.5 inches.

The actual distance between the historical markers in 4.5 inch is

$4.5 \text{ inch}=4.5\times 4\text{ miles}$

$4.5 \text{ inch}=18\text{ miles}$

Therefore, The actual distance between the historical markers is 18 miles.
