arc ACD = 120°

Step-by-step explanation:

Angle ACD = 120°

From cyclic quadrilaterals, opposite angles are supplementary.

angle ABD + angle ACD = 180

120 + ACD = 180

ACD = 60

Let the centre be point O.

Then arc ACD is the same as the angle AOD

From chord properties,

angle ABD = angle AOD /2

or

AOD = 2 * ABD = 2*60 = 120°

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
