And I THINK you might be right.

jhonyy9:

@XioGonz than you say me how you get this answer - the way - i will say you than is right or not

jhonyy9:

there is a key to solve this problem

XioGonz:

The first thing I did was 3959² + x² = (3959 + 3.1)²

imnotsmartlol:

im pretty sure ur right cuz ur smart

XioGonz:

Next I did 3959² + x² = 3959² + 2.(3959 * 3.1) + 3.1²

XioGonz:

So x² = 2.(3959 * 3.1) + 3.1²

XioGonz:

x² = 24555.41

jhonyy9:

sorry what is this 3,1 i dont understand

XioGonz:

And x ≈ 156.7 miles

\(\color{#0cbb34}{\text{Originally Posted by}}\) @XioGonz And x ≈ 156.7 miles \(\color{#0cbb34}{\text{End of Quote}}\) mate just multiply the 9

XioGonz:

Ohhhhhhhhhhhhh I put it wrong, it's supposed to be 10.2

jhonyy9:

The first thing I did was 3959² + x² = (3959 + 3.1)² 3,1 what is there ?

bruhman7624:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 The first thing I did was 3959² + x² = (3959 + 3.1)² 3,1 what is there ? \(\color{#0cbb34}{\text{End of Quote}}\) 3.1

XioGonz:

So it's 3959² + x² = (3959 + 10.2)²

jhonyy9:

the key pls how can use there pythagora ?

bruhman7624:

add them then do to the power of 2\(\color{#0cbb34}{\text{Originally Posted by}}\) @XioGonz So it's 3959² + x² = (3959 + 10.2)² \(\color{#0cbb34}{\text{End of Quote}}\)

jhonyy9:

@XioGonz the key where is the right angle to use pythagora ?

XxFrancisco14:

PRetty sure

jhonyy9:

@XioGonz why is there right angle ?

XioGonz:

I'm going to redo the problem.

jhonyy9:

remember pls the radius on the tangent point of a tangent line on a circle creat always a right angle

XioGonz:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 remember pls the radius on the tangent point of a tangent line on a circle creat always a right angle \(\color{#0cbb34}{\text{End of Quote}}\) Ohh
