Answer:

10

Step-by-step explanation:

This triangle is divided into 2 identical rigth triangles.

We will use the pythagorian theorem:

●8^2+ (12/2)^2 =x^2

● 64 + 36 = x^2

● x= 10

So x is 10

Answer:

x=10

Step-by-step explanation:

We can use the Pythagorean theorem to find x

The height meets the base at a right angle

The base is bisected ( cut in half) so the base is 6 the height is 8

a^2 + b^2 = c^2

6^2 + 8^2 = x^2

36+64 = x^2

100 = x^2

Taking the square root of each side

sqrt(100) = sqrt(x^2)

10 = x

You are enlarging a photograph to make a poster. The posterwill be similar to the original photograph. The photograph is6 inches
natka813 [3]

Answer:

Poster’s perimeter = 150 in

Step-by-step explanation:

Given:

Width of poster = 2.5 ft = 2.5 × 12 = 30 in

Find:

Poster’s perimeter.

Computation:

Height of poster = [30×6]/4

Height of poster = 45 in

Poster’s perimeter = 2 [Width of poster + Height of poster]

Poster’s perimeter = 2 [30+45]

Poster’s perimeter = 2 [75]

Poster’s perimeter = 150 in

A particular algebra text has a total of 1382 pages which is broken into two parts the second part of the book has 64 more pages
AlladinOne [14]

Answer:

the first part of the book has 659 pages and the second part has 723 pages

Step-by-step explanation:

First we have to raise 2 equations, one that shows us the relationship between one part of the book and the other, and another equation that shows us that together they give us the total of pages

x = second part

y = first part

x = y + 64

x + y = 1382

As the first equation tells us that x = y + 64 we will replace x in the second equation with (y + 64)

x + y = 1382

(y + 64) + y = 1382

y + y = 1382 - 64

2y = 1318

y = 1318/2

y = 659

now we replace in the first equation to y by its value

x = y + 64

x = 659 + 64

x = 723

so the first part of the book has 659 pages and the second part has 723
