Answer:

She has to buy 48 inches of ribbon

Step-by-step explanation:

We know that the pillow is a square with an area of 144. This means that all the side lengths must be the same. If we take the square root of 144 we get 12 which is the length of one side of the square. Because there are four sides to a square, we multiply this by 4. So 12 x 4 = 48 inches of ribbon.

Given the figure below, find the values of x and z.
zysi [14]

Answer:

x= 2

z = 106

Step-by-step explanation:

By the definition of vertically opposite angles,

(10x + 54)° = 74° [Pair of opposite angles made by two intersecting lines]

10x = 74 - 54

10x = 20

x = 2

z° + 74° = 180° [Pair of supplementary angles]

z = 180 - 74

z = 106

mr Goodwill [35]

Answer:

<em>FG - it is midline. FG = 5.</em>

Explanation:

<em>A midline in a triangle is a line segment connecting the midpoints of two sides.</em>

<em>A midline is half the length of the side to which it is parallel.</em>

<em />\dfrac{CE}{FG} =2\\\\ \dfrac{9x-26}{7x-23} =2\\\\9x-26=2(7x-23)\\9x-26=14x-46\\14x-9x=46-26\\5x=20\\x=4<em />

<em>CE = 9 · 4 - 26 = 10</em>

<em>FG = 10/2 = 5</em>
