Answer:

angle AOD + 170=180 (sum of angles on a straight line)

angle AOD=180-170

angle AOD=10

Angle BOC(4x)+ 170= 180 (sum of angles on a straight line )

angle BOC(4x) =180-170

4x=10

4x/4=10/4

x=2.5

Monica has a 24
melamori03 [73]

Answer:

The fraction of frame did Monica paint blue is \frac{3\sqrt{6}}{2}  

Step-by-step explanation:

Given as :

The area of square frame = A = 24 square inches

Monica paint \frac{3}{4} of one side of the frame blue

Let the measure of one side of frame = x

So, <u>From Area of square</u>

Area = side × side

Or, A = x × x

Or, x ² = 24

∴  x = \sqrt{24} = 2\sqrt{6}

So, Measure of each side = x = 2\sqrt{6}

Now, As Monica paint \frac{3}{4} of one side of the frame blue

So, The painted part = \frac{3}{4} ×  2\sqrt{6}

∴ The painted part = \frac{3}{2} × \sqrt{6}

I,e The fraction of painted blue = \frac{3\sqrt{6}}{2}

Hence, The fraction of frame did Monica paint blue is \frac{3\sqrt{6}}{2}  Answer

Sachiko is framing the border of a square picture. If she knows the area of the picture, how could Sachiko determine the amount
tatyana61 [14]

Answer:

Set the area equal to x2, solve for x, and then multiply the value of x by 4.

Step-by-step explanation:

The area of the picture is given by

A = s^2 where s is the side length

Let the side length be x

A = x^2

Take the square root of each side

sqrt(A) = sqrt(x^2)

x = sqrt(A)

We want to find the perimeter since we are framing the border

P = 4s since the picture is a square

P = 4 * x
