5. Angle formed outside of a circle by intersection
a tangent and secant

Answer 2

Okay thanks

Answer 3

can you apply that to your question?

We're trying to find arc PM
that's basically 'c' in my image

and we know the angle 'a' is 59
and the arc 'b' is 21

Answer 4

Okay now I get it

Answer 5

what do you get

Answer 6

On how to solve the equation I think
so like 1/2=(c-21)? or

Answer 7

59*=1/2

Answer 8

okay so I did 59=1/2 times c-21 and got
=21?

Answer 9

you're on the right track

59 = 1/2 (c-21)

now to get rid of the 1/2, multiply both sides by 2

59 * 2 = 2 * 1/2 * (c-21)

what is 59 * 2 = ?
and 2 * 1/2 is going to be 1

Answer 10

well 59 times 2 is 118
So then 118=1 times c-21
=139?

Answer 11

As final answer?

Answer 12

That is correct!
