The sum is 500 because 1000 split betwwen even and odds are even making 500
To determine if a line is perpendicular to another, you must first determine the slope...
m = y1-y2/x1-x2
m of FK = 3-5/3-6 = -2/-3 = 2/3
m of FJ = 3-2/3-8 = 1/-5
m of FL = 3-0/3-5 = 3/-2
m of KJ = 5-2/6-8 = 3/-2
m of KL = 5-0/6-5 = 5
m of JL = 2-0/ 8-5 = 2/3
In order for two lines to be perpendicular, their slopes must be opposite reciprocals...
FK is perpendicular to FL
FK is perpendicular to KJ
JL is perpendicular to FL
JL is perpendicular to KJ
FJ is perpendicular to KL
Answer:
8
Step-by-step explanation:
Answer:
As radius is perpendicular to tangent,
By pythagoras theorem :
x² = (x + 9)² - 15²
x² = x² + 18x + 81 - 225
18x = 207
x = 11.5
