Answer:
<em>3.2 miles</em>
Step-by-step explanation:
Given the coordinate point (6,2) and (3,3)
The distance between the two points is expressed using the formula;
D = √(x2-x1)²+(y2-y1)²
D = √(3-2)²+(3-6)²
D = √1²+(-3)²
D = √1+9
D = √10
D = 3.2
<em>Hence the distance (in a straight line) between the library and the school rounded to the nearest tenth is 3.2 miles</em>
The Pythagorean theorem tells you
... (height of ladder)² + (distance from house)² = (length of ladder)²
... (height of ladder)² + (8 ft)² = (12 ft)²
... height of ladder = √(12² - 8²) ft
... height of ladder = √80 ft ≈ 8.94 ft
