D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1
Gordon read a total of 35 pages, so if there is p pages read per day and 10 days you'd have something that looks like this: 35 = 10p.
I billion hamburgers would be eaten in 1 billion minutes, which would translate to 1903 years.
Answer:
120°
Step-by-step explanation:
The arc ABC is twice that of the angle created at D. This is the central angle theorem extension.
So we can say that arc ABC = 2* 120 = 240
<em>We know total circle angle is 360 degrees so, arc ADC + arc ABC = 360</em>
<em />
<em>Hence,</em>
<em>arc ADC + 240 = 360</em>
<em>arc ADC = 360 - 240 = 120</em>
