Question

Lines JK, KL, and LJ are all tangent to circle O. The Diagram is not drawn to scale.

If JA = 10, AL = 23 and CK = 9, what is the perimeter of triangle JKL?

a. 84
b. 66
c. 42
d. 38

Is the answer 84? Please explain how you got the answer.

Answer 1

This is the concept of perimeter of geometric figures;
We are required to approximate the perimeter of the triangle given if JA=10, AL=23, CK=9
Summing the above measures we get;
10+23+9=42
assuming that this is half the perimeter of the whole triangle then;
perimeter=2*42=84
The answer is A
