a. write the expression without the absolute value sign: |3c|, where c≥0

b. simplify the expression |ab| if, a> 0 and b> 0

c. simplify the expression |ab| if, a< 0 and b> 0

  a) 3c

  b) ab

  c) -ab

Step-by-step explanation:

For x > 0, |x| = x. This lets us remove the absolute value symbols in parts (a) and (b):

a. |3c| = 3c . . . when c > 0

b. |ab| = ab . . . when ab > 0

c. The absolute value function returns the opposite of its argument when that argument is negative:

  |ab| = -ab . . .  when ab < 0

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
