Normally 18/2 is 9, but since we’re dividing by a negative, the 9 becomes negative.

What is the area of the red region?
Nitella [24]

Answer:

≈ 57.13cm^{2}

Step-by-step explanation:

Area of Circle:

A = π r^{2}

π (4)^{2}

π (16)

≈ 50.27cm^{2}

Area of Square:

A = l(w)

8(8) = 64 cm^{2}

Area of each corner:

64 - 50.27 = 13.73cm^{2}

13.73 ÷ 4 ≈ 3.43cm^{2}

Area of Red:

50.27 + (3.43(2)) ≈ 57.13cm^{2}

HELPPP PLEASEEEEEE!!!!!!!!!1

Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:

x+2x+21=180

Combine like terms:

3x+21=180

Subtract 21 from both sides:

3x=159

Divide both sides by 3:

x=53

Therefore, the value of x is 53 degrees.
