Answer:
k/11 = 7
Step-by-step explanation:
K is being divided by 11 and equals 7
|x+y| = |-8+(-13)| = |-8-13| = |-21| = 21
Use Pythagorean Theorem:
a² + b² = c²
"a" is one side of the right triangle.
Its length is: radius of larger circle minus radius of smaller circle: (11 - 3 = 8)
The distance between the center of the circles creates the hypotenuse (17)
8² + b² = 17²
b² = 225
b = 15
Answer: the length of the common external tangent is 15.
