lol, there are three.
Step-by-step explanation:
thanks for the points I guess.
Answer:
B. (x-9)^2 + (y + 7)^2 = 4
Step-by-step explanation:
The standard form of a circle is (x-h)^2 + (y-k)^2 = r^2. Hopefully you can memorize that, because it's very helpful in these problems!
(h,k) is our center, and r is our radius, so plug those values into the standard form:
(x - 9)^2 + (y + 7)2 = 2^2
2^2 = 4, so
<u>B. (x - 9)^2 + (y + 7)2 = 4 is our answer!</u>
add them together then divide by 5
81 +86 +81 +76 +71 = 395
395/5 = 79
your average was 79

Hope that helps
Answer:
Step-by-step explanation:
a + 143 = 180 {Linear pair}
a = 180 - 143
a = 37
37 + 93 + b = 180 {Angle sum property of triangle}
130 + b = 180
b = 180 - 130
b = 40
c + b = 90
c + 40 = 90
c = 90 - 40
c = 50
d + 120 = 180 {Linear pair}
d = 180 - 120
d = 60
? = 60 + 40 {Exterior angle property of triangle}
? = 100
