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? explain how you got the answer.

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

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

The answer is a hope i
