Question

Circle problem

Answer 1

The two angles marked in blue are central angles of the circle.

They are vertical angles and are congruent which means they have the same measure.

Answer 2

The measure of a central angle is the same as its intercepted arc. See attached theorem.

Answer 3

So, 70+70=140

Answer 4

@sbuck98 What do you think is the measure of <FOE ?

Answer 5

40? because 180-40=40

Answer 6

>>70+70=140 is a true statement but not the measure of <FOE.

Answer 7

m<ZOH = 70.

m<ZOH = m<FOE

m<FOE = ?

Answer 8

I'm not sure how to find it

Answer 9

>>40? because 180-40=40

Please read what I am posting.

Answer 10

This is a way to find it:

m<ZOH = 70.

m<ZOH = m<FOE

m<FOE = ?

Answer 11

If two angles have the same measure and one of them is 70, what is the other?

Answer 12

70

Answer 13

@Directrix

Answer 14

then 180-70=110 so that's my answer correct?

Answer 15

>>70 Yes, that is what I got.

Answer 16

I don't know what is going on here:

>> then 180-70=110 so that's my answer correct?

Answer 17

a whole circle is 180 so I was thinking I had to subtract to find the actual angle degree, sorry I was wrong....

Answer 18

>>110

That is the measure of < EOZ. We are not asked to find that.

Answer 19

Don't be sorry. Wrong answers eventually lead to the correct answer if we keep working.

>>a whole circle is 180

The entire circle is 360 degrees.

Answer 20

@xavier123

Answer 21

<FOE and <ZOH are equal... hence, 70 :)

Answer 22

ok!
