Answer:
L = 5
Step-by-step explanation:
use Pythagorean Theorem:
L² + (5)² = (10)²
L² + 25(2) = 100(3)
L² + 50 = 300
L² = 250
L = = · = 5
1 because he HAD 5 and if he gave his friend 4 than he has 1 left, 5-4=1 my friend.
Distance = r x t ===> t=d/r
Distance (after 2 hours driving @30mil/hr) = 2 x 30 = 60 Mil
To drive same distance (60) with r = 50, the time needed is 60/50 =1.2 hrs
If the polygons are similar then the sides are in proportion.
Therefore we have the equations:
