Answer:
√34
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(10 - 5)² + (2 - 5)²
√(5)² + (-3)²
√25 + 9
√34
= 5.8
Answer:
C) 1/5
Step-by-step explanation:
Slope=(y2-y1) /(x2-x1)
(-5,5)...........x1=-5, y1 =5
(5,7).............x2=5, y2=7
Slope=(7-5)/(5-(-5))
Slope=2/(5+5)
Slope=2/10
Slope=1/5
Answer:
Pretend that H is the midpoint of AB, connect O and H
=> OH is the median of ΔOAB
Since we know that OA = OB => ΔOAB is an isosceles triangle
=> OH is also the height of ΔOAB
=> ∠OBA = ∠OAB = (180° - ∠AOB)/2 = (180° - 120°)/2 = 60°/2 = 30°
Now look at ΔOHB (that you create by connecting O and H)
We have:
cos30° = BH/OB
=> BH = cos30° · OB = √3/2 · x = (√3 x)/2
Because we have H as the midpoint of AB, we know that:
AB = 2 · BH = 2 · (√3 x)/2 = √3 x
So the answer is B
