Question

Geometry help, please!!!!

@Shadow

Answer 1

Just searching for le formula

Answer 2

Okay, thank you

Answer 3

@Vocaloid How would you do this one?

Answer 4

Cause here's what I'm tempted to do.

A and S make the diameter. Thus arc ARS is 180 degrees. So AR + RB + BS = 180

We have AR and RB. We solve for BS algebraically.

Answer 5

Then to solve for RS, we just do RB + BS.

Answer 6

seems simple-ish enough

Answer 7

But hold the phone.

Answer 8

*holds phone*

Answer 9

Okay. We're going to do something Vocaloid suggested. My brain is KFC basically so I'm going to copy and paste she wrote, and what I wrote.

This idea follows the logic of "arcs AR and BS are equal on account of the chords being equal " - Vocaloid

Thus you would do:

\[AR + RB = RB + BS\]

Answer 10

okay, lemme get the numbers

Answer 11

AR(55) + RB(66) + AB (8) + RS(8) =137

Answer 12

What

Answer 13

Arc lengths

Answer 14

Don't add arc lengths and chords. Just the arc lengths.

Answer 15

okay

AR(55) + RB(66) = RB(66) + BS(?)

Answer 16

Yes

Answer 17

Once you get BS, you can add it to RB and get RS

Answer 18

and how would i get the length of bs?

Answer 19

\[55 + 66 = 66 + BS\]

Solve for BS

Answer 20

okay

Answer 21

55+66=121

Answer 22

Okay, and then what do you do

Answer 23

66+BS

Answer 24

^which is equal to

Answer 25

59?

Answer 26

is that wrong?

Answer 27

How did you get 59

Answer 28

I added together the measurments for the arcs and subtracted what i had from 180, which was probably wrong.

Answer 29

AR + RB = RB + BS

55 + 66 = 66 + BS

121 = 66 + BS

BS = 55

Just shy of 180, so glad we didn't do my idea

RB + BS

66 + 55 = 121

Answer 30

i was close XD

Answer 31

so what do we do now?

Answer 32

We're done. Review what I wrote.

Answer 33

okay, thanks

Answer 34

both sides equal 121
