Given,  

∠AOE = 30°

∠DOB = 40°

So, ∠EOD = 180 - (30+40)           [angles on a straight line]

                =  180 - 70

                =  110

∠EOD = ∠COF                             [ vertically opposite angle]

∴ ∠COF = 110°

91°-32°=
59°
The line EF total angles must equal 180°. Therefore angle EOB is 89°, (180-91). Then line AB must also equal 180°. And angle EOB is 89° and angle COA is 32°. Take 89+32 which is 121. 180-121=59. Finally, that leaves angle COE with an angle measure of 59°.

You have to make 1000 buttons.the diameter of the button is 9cm but you have to find it’s area.its $15/m squared and you have to
Semmy [17]

Answer:

$95.38

Step-by-step explanation:

step 1

Find the area of one button

The area is equal to

A=\pi r^{2}

we have

r=9/2=4.5\ cm ---> the radius is half the diameter

Convert to meters

r=4.5\ cm=4.5/100=0.045\ m

assume

\pi =3.14

substitute

A=(3.14)(0.045)^{2}\\A=0.0063585\ m^2

step 2

Find the area of 1,00 buttons

Multiply by 1,000

A=0.0063585(1,000)=6.3585\ m^2

step 3

Find the cost

Multiply $15 per square meter by the total area of 1,000 buttons

(15)6.3585=\$95.38

Ganezh [65]

Answer:

x = 2y - 7

x + y = 47
