Answer:

76 because the angles must add up to 360

Answer:

x = 76

Step-by-step explanation:

All angles must add up to 360 degrees. So, we add the angles we already have.

104 + 123 + 57 + x= 360 we will solve for x

284 + x = 360  add all known values on the left

x = 76 we subtract 284 from both sides to isolate x

To check our answer, we add all values

104 + 123 + 57 + (76) = 360 This is correct. :)

Find the area of the shaded region
Dimas [21]

The area of the shaded region is 15.453 square units.

Step-by-step explanation:

Step 1:

The given shape consists of a rectangle and two circles.

The length of the rectangle is given as 12 cm. Both the diameters of the circles equal 12 cm. So each circle has a diameter of 6 cm and thus a radius of 3 cm.

The diameter of the circle is equal to the width of the rectangle.

So the rectangle has a length of 12 cm and a width of 6 cm. The circles have radii of 3 cm each.

Step 2:

The area of the rectangle = (l)(w) = (12)(6) = 72 square cm.

The area of each circle = \pi r^{2}  = (3.1415)(3^{2} ) = 28.2735 square cm.

The area of both circles =2(28.2735) = 56.547 square cm.

The area of the shaded region is the difference between the area of the rectangle and the area of both circles.

The area of the shaded region = 72 - 56.547 = 15.453 square units.

The area of the shaded region is 15.453 square units.
