Does anyone know how to do this?

Answer 1

Are you given that this an equilateral triangle ? (that all sides of the triangle are equal )

Answer 2

all I have is what I posted

Answer 3

Okay, so you need to set the triangle up in a ratio

Answer 4

and since all tangents are congruent at the same circle, that means both sides (JL and JK) are congruent

Answer 5

okay

Answer 6

Since JL is congruent to LK by tangents congruent, that means this triangle is an equilateral triangle

Answer 7

Now that you know that this triangle is equilateral, can you solve it?

Answer 8

so then 13*2 + 19*2 + 7*2

Answer 9

no, Equilateral triangles imply all sides are equal

Answer 10

so its 78

Answer 11

oh wait

Answer 12

I still got 78

Answer 13

ok, CK is congruent to BK because tangents are congruent.

Answer 14

AL is congreunt to LC by tangents are congruent

Answer 15

AJ and JB are congruent by tangents are congruent

Answer 16

Can you do that?

Answer 17

I'm so lost

Answer 18

oh. It is 78!! hahaha oops

Answer 19
