Try to find r first. Then use trigonometry and the arc length formula.

[tulip linden]

How do we find r?

[wispy tangle]

The Pythagorean Theorem.

[tulip linden]

Alr Ty

[tulip linden]

Do we do it like this ?

Still bemused how do we apply the Pythagorean theorem here

[wispy tangle]

On the right triangle...?

OPQ?

[wispy tangle]

For arclength, yeah.

[tulip linden]

For finding r

We don’t have the angle

[wispy tangle]

You could do that, but it’s over complicating it.

[wispy tangle]

Again.

[tulip linden]

We only know B Q

We don’t have theta nor the r

Then how do we apply the theorem?

@wispy tangle

[wispy tangle]

Hm?

We have a right triangle.

OPQ.

[tulip linden]

Yeah that’s fine

[wispy tangle]

5^2+(r+6)^2=(r+7)^2.

[tulip linden]

Thank you sooo much
