Answer:
C 36
Step-by-step explanation:
1/2(base)(height)
1/2(8)(9)
1/2(72)
=36
Although thisnumber<span> can be expressed as a fraction, we need more than to be a </span>rational number<span>. The fraction's numerator and denominator must both be integers, and √2 cannot be expressed as an integer</span>
You have to complete the squares on both the x terms and the y terms in order to solve this. Move the 20 over to the other side so it's negative. Group the x terms together and complete the square to get (x^2+2x+1) and then do the same with the y terms: (y^2-4y+4). You have to add 1 and 4 to other side with the 20 to get a 25. Then create 2 perfect square binomials within each x and y value to get the vertex coordinates: (x+1)^2 + (y-2)^2 = 25. This tells us that the vertex is located at (-1, 2) and the radius is the square root of 25 which is 5.So the answer is the first choice above.
5n = 10^2
n = 20 Because 5 × 20 = 100
And angle is formed by the union of two vertices or corners.
