Answer:

B supplementary

C adjacent

Step-by-step explanation:

Vertical angles are across from each other and are equal False

Supplementary angles add to 180 degrees (if next to each other they form a straight line) True

Adjacent angles are next to each other True

Complementary angles add to 90 degrees (from a right angle) False

The first question is this: the smallest square is square A, and that is 9 units. and square E is two times that, and so on.

Square A's side length is 9 units and the area is 81.
Square E's side length is 18 and the area is 324.
Square C's side length is 27 and the area is 729.
Square B's side length is 36 and the area is 1,296.
Square D's side length is 45 and the area is 2,025

Find the equation of a circle in standard form that is tangent to the line x = -3 at (-3, 5) and also tangent to the line x = 9.

Sedaia [141]

Answer:

(x -3)² +(y -5)² = 36

Step-by-step explanation:

The center is on the vertical line halfway between the given vertical lines, so is at x=3. It is also on the horizontal line through the point (-3, 5), so is at y=5. The center is 9-3=6 from either tangent line, so this is the radius.

For center (h, k) and radius r, the circle's equation is ...

(x -h)² +(y -k)² = r²

For (h, k) = (3, 5) and r=6, the equation is ...

(x -3)² +(y -5)² = 36 . . . . . . . . does not match any choice written here

If a circle has a diameter of 30 meters, which expression gives its area in square meters?

Genrish500 [490]

Area of a circle is given by $\pi r^{2}$ where $r$ is the radius

Radius of a circle is half of the diameter

We have the diameter 30 meters, so the radius is 30÷2=15 meters

Area of the circle = $\pi (15)^{2}$

Note: The option given doesn't show the $\pi$ symbol but it seems like the correct answer is option A
