Determine which set of numbers can be the measures of the sides of a triangle.
finlep [7]

Answer:

A. 13, 10, 16

Step-by-step explanation:

If three sides of triangle have measures a, b and c, then

a+b>c\\ a+c>b\\b+c>a

Check all options:

A. a=13, b=10, c=16

Thus,

a+b=13+10=23>16=c\\a+c=13+16=29>10=b\\b+c=10+16=26>13=a

This option is true

B. a=1, b=2, c=3

Then

a+b=1+2=3=c, but a+b must be greater than c, so

this option is false

C. a=5.2, b=11, c=4.9

Then

a+c=5.2+4.9=10.1 but a+c must be greater than b, so

this option is false

D. a=208, b=9, c=219

Then

a+b=208+9=217 but a+b must be greater than c, so

this option is false
