Question

Lines CD and DE are tangent to circle A shown below.

Answer 1

If CE is 126°, what is the measure of ∡CDE?
126°
63°
117°
54°

Answer 2

@Mertsj

Answer 3

The angle formed by two tangents that intersect outside the circle is the difference of the intercepted arcs divided by 2

Answer 4

so what are u saying

Answer 5

See attachment for theorem needed.

Answer 6

I don't get how to set it up

Answer 7

How many degrees in a circle?

Answer 8

360

Answer 9

So if the arc CE is 112, what does that leave for the arc CBE?

Answer 10

248

Answer 11

Subtract the first arc (112) from the second one(248) . When you get that answer, divide it by two.

Answer 12

68

Answer 13

That's what I got.

Answer 14

but it said If CE is 126°, what is the measure of ∡CDE?
126°
63°
117°
54°

Answer 15

do I do the same thing

Answer 16

Then do the problem again using 126 for arc CE

Answer 17

ok

Answer 18

54

Answer 19

What is arc CE?

Answer 20

112

Answer 21

I made a mistake. Yes. I agree with 54

Answer 22

tHAnk you

Answer 23

In circle A shown below, m BC is 71° and m EF is 78°.

Answer 24

What is m∡FDE?

35.5°


74.5°

39°

78

Answer 25

@Mertsj

Answer 26

The angle formed by two chords is 1/2 the SUM of the intercepted arcs.

Answer 27

WHAT ARE U SAYING

Answer 28

Do you know what chords of a circle are?
