Answer 1

Welcome to QC!

We first want to solve for x

Remember that circles add up to 360 degrees

So just add everything and set it equal to 360

\((25x-4)+(20x+4)+(15x)=360\)

Do you know how to solve this?

Answer 2

would the answer be x=7.6?

Answer 3

Not quite

Answer 4

\(25x-4+20x+4+15x=360\)

Reorganizing to have common factors

\(25x+20x+15x-4+4=360\)

Then combining terms

\(60x=360\)

Can you solve from here?

Answer 5

x=6 right?

Answer 6

Right

Answer 7

Now for a

First, substitute x into that equation

Answer 8

124?

Answer 9

Yes, now because \(\angle BCA\) is inscribed to the back, you divide 124 by 2

Answer 10

which would become 62

Answer 11

Yes, that is your answer to a

Answer 12

Now for b

Substitute x into 15x

Answer 13

It would become 90 which then divide by two, so the final answer would be 45

Answer 14

Looks good, that is b

Now for c do the same thing with the final measurement

Answer 15

For b the answer would be 73

Answer 16

Wait so for the second question, is it the same as number 1?

Answer 17

This is a)

Answer 18

Does that mean you cannot help me anymore?

Answer 19

I can, I was just clarifying the answers

Answer 20

Oh sorry
