An angle is formed by two rays with a common endpoint. The endpoint is the vertex. And the two rays are the sides
Example name - PQR Q is the certex
Answer:
Option D: 6:12 is correct answer.
Step-by-step explanation:
We can find the simplest form of ratio to compare it with the given ratios.
According to given statement,
The ratio is:

Now we will check if the given options can be simplified to 1:2
So,
Option A:

Option B:

Option C:

Option D:

As we can see that 6:12 can be simplified to 1:2 which is same as 2:4 so it will make the same shade of purple.
Hence,
Option D: 6:12 is correct answer.
Answer:
5
Step-by-step explanation:
first multiply 3 by 7 as 3x7=21
again find the square of 4 as 4^2=16
finally, subtract 16 from 21 as 21-16= 5
<span>The number 123,000,000,000 in scientific notation is written as : 1.23 * 10 to the eleventh power.
Thats an example to help you out ;)

<span>The first part of the quadratic formula, x = - b/2a, is the equation of the axis of symmetry, and the x-coordinate of the vertex. </span>
<span>In standard form: - 2x² + 8x - 5 = 0, a = - 2, b = 8, c = - 5 </span>
<span>The axis of symmetry: x = - 8/2(- 2) = - 8/- 4 = 2 </span>
<span>Go back and solve for y to find the y-coordinate of the vertex. </span>
<span>y = - 2(2)² + 8(2) - 5 </span>
<span>y = - 2(4) + 16 - 5 </span>
<span>y = - 8 + 16 - 5 </span>
<span>y = 3 </span>
<span>Vertex is (2, 3)</span>
