Answer 1

Please

Answer 2

is that an 'a'?

Answer 3

yes

Answer 4

what does that 4 in the middle signify?

Answer 5

the numbered angle

Answer 6

1/2 the sum of the intercepted arcs

Answer 7

1/2(3a+4a)=3.5a

Answer 8

????????

Answer 9

????????

Answer 10

What is it you don't understand? The measure of one intercepted arc is 3a. The measure of the other intercepted arc is 4a. 3a+4a is 7a. One-half of 7a is 3.5a.

Answer 11

I know i did that but its not one of the answers

Answer 12

What are the answers? Maybe it says
\[\frac{7}{2}a \]

Answer 13

or
\[\frac{7a}{2}\]

Answer 14

A=81 b=90 c=94 d=102

Answer 15

Or maybe it wants you to all up all the arcs and solve for a

Answer 16

E2020 is never specific

Answer 17

\[4a+4a+7a+3a=360\]

Answer 18

\[18a=360\]

Answer 19

\[a=20\]

Answer 20

Its keeps saying math processing error

Answer 21

\[3.5a=3.5(20)=70\]

Answer 22

type what youre treying to tell me in words

Answer 23

*trying*

Answer 24

The sum of the arcs in a circle is three hundred sixty degrees. Add all the arcs and set the sum equal to three hundred sixty degrees. Then solve for a and proceed from there. After you know the numerical value for "a" you can find each arc and from that each angle.
