Question

Point C is the center of the circle. If angle ACB measures (4x+12)° and AB measures (x+13)°. Find x.

Answer 1

Measure of arc equals its central angle!

Answer 2

so,
\(4x+12 =x+13\)
find x from here :)

Answer 3

x=1/3? THANKYOU SO MUCHH

Answer 4

would you PLEASE help me with another one :)??

Answer 5

correct!
welcome ^_^

Answer 6

sure

Answer 7

Point C is the center of the circle. What is the measure of arc ADB if <ACB is equal to 102°?

Answer 8

same thing

since, measure of arc = central angle,
first find measure of arc AB
what would it be ?

Answer 9

I dont know :( because they dont dive us two values, only one

Answer 10

arc AB = angle ACB = 102

Then
notice that arc AB and arc ADB form an entire circle!

so
arc AB + arc ADB = 360

find arc ADB from here :)

Answer 11

258?

Answer 12

thats correct :)

Answer 13

:O THANKYOUUU!

Answer 14

welcome ^_^
happy to help :)
