In a triangle, the three interior angles always add to 180°
x = 180 - 28 - 65 = 87° 
(Choice B)

10
x = 180 - 51 - 38 = 91°
y = 180 - x = 180 - 91 = 89°
z = 180 - 89 - 60 = 31°

A rotating lawn sprinkler sprays water in a circular area of grass, as shown in the picture. The diameter of the circular area o
Ksenya-84 [330]

Answer:

The area the sprinkler sprays with water is 201.06 square feet.

Step-by-step explanation:

Step 1; It is given that the diameter of the circular area of grass that the sprinkler sprays with water is 16 feet. The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.

Radius of the circle = Diameter of the circle / 2 = 16 feet / 2 = 8 feet.

Step 2; The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.

Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet.

For the function illustrated above, what is the domain? A{1, 2, 3, 4, 9, 12} B{1, 4, 9, 12} C{2, 3, 4} D{4, 9}
marshall27 [118]

Answer:

The correct option is C

C)  (2,3,4)

Step-by-step explanation:

Domain can be defined as the set of all possible values of input, for which we can calculate the values of output. The values of input are independent, while the values of output are dependent on the values of input.

In the diagram, we can see that the arrow represents that for a certain number in A, we get a number from B. Which means that A represents the input while B represents the output.

As A is the input, all values of A form the domain of the function, which means that domain in {2,3,4}
