If x - 7 = -13, we need to get x by itself to solve this equation. To get x by itself, we can add 7 to each side (that way x will be by itself, and only on one side of the equation).

x - 7 + 7 = -13 + 7

We can add 7 to each side without changing the quantity because we do it to BOTH sides.

x = -13 + 7

Since -13 + 7 is -6,

x = -6

Find x❤❤<br><br> I Will mark brainliest who answer first

andre [41]

Value of x is 35°

Step-by-step explanation:

Step 1: Since the line segment is a perpendicular bisector, the angle formed is equal to 90° and two triangles are also formed.

Find x using the property of triangles that sum of angles of a triangle is 180°

⇒ x° + 55° + 90° = 180°

⇒ x° + 145° = 180°

∴ x = 180 - 145 = 35°

A rectangle or piece of paper has a width is 3 inches less than its link it is cut in half along a diagonal to create two congru

kolezko [41]

The length and width of the rectangle is 11 in and 8 in respectively.

Step-by-step explanation:

Given,

The width of a rectangle is 3 in less than the length.

The area of each congruent right angle triangle = 44 in²

To find the length and width of the rectangle.

Formula

The area of a triangle with b base and h as height = $\frac{1}{2}$ bh

Now,

Let, the width = x and the length = x+3.

Here, for the triangle, width will be its base and length will be its height.

According to the problem,

$\frac{1}{2}$ ×(x+3)×x = 44

or, $x^{2} +3x = 88$

or, $x^{2} +3x-88 = 0$

or, $x^{2}$ +(11-8)x-88 = 0

or, $x^{2}$ +11x-8x-88 =0

or, x(x+11)-8(x+11) = 0

or, (x+11)(x-8) = 0

So, x = 8 ( x≠-11, the length or width could no be negative)

Hence,

Width = 8 in and length = 8+3 = 11 in
