The distance between the house and the subway is given by:
d=√[(x-x1)²+(y-y1)²]
Thus given the coordinates:
(-1,9) and (2,-4)
thus
d=√[(2-(-1))²+(-4-9)²]
d=√[(3)²+(-13)²]
d=√[9+169]
d=√178
d=13.34 ~13 units
Answer: D) 13
Answer:
x = 27°
Step-by-step explanation:
<em>l ║ m </em>Given
(x + 72) + (3x) = 180° If parallel line then same-side angles = 180°
4x + 72° = 180°
4x = 180° - 72°
4x = 108°
x = 108°/4
x = 27°
Answer: x=-14
Step-by-step explanation:
Answer:
x = 4.2
Step-by-step explanation:
72 + 10x = 114
10x = 114 - 72
10x = 42
x = 42/10
x = 4.2
