Answer:

140 degrees

Step-by-step explanation:

The sum of the angles on a line is 180. Since we know one of the angles is 40, you do 180-40 to figure out the other angle (DCB). The answer is 140.

Answer:

x = 140 \:  \: degrees

Step-by-step explanation:

<em>Angels</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>straight</em><em> </em><em>line</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em>

<em>Let</em><em> </em><em>the</em><em> </em><em>DCB</em><em> </em><em>angle</em><em> </em><em>be</em><em> </em><em>x</em>

<em>Given</em><em> </em><em>that</em><em>,</em>

<em>ACD</em><em> </em><em>angle</em><em> </em><em>=</em><em> </em><em>4</em><em>0</em><em>°</em>

<em>Let's</em><em> </em><em>solve</em><em> </em><em>now</em><em>,</em>

<em>40 + x = 180 \\ x = 180 - 40 \\ x =1 40 \:  \:  \: degrees</em>

Abdul is creating a cushion that is 1 foot by 2 feet by 3 feet. He wants to find the least amount of fabric he will need to cove
netineya [11]

Answer:

The least amount of fabric are 22 square feet

Step-by-step explanation:

we know that

The surface area of a rectangular prism is given by the formula

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

Let

L ---> the length pf the prism

W ---> the width of the prism

H ---> is the height of the prism

Let

L=2\ ft\\W=3\ ft\\H=1\ ft

Find the area of the base

B=LW=(2)(3)=6\ ft^2

Find the perimeter of the base

P=2(L+W)=2(2+3)=10\ ft

Find the surface area

SA=2(6)+10(1)=22\ ft^2

therefore

The least amount of fabric are 22 square feet
