A triangle has two sides of length 9 and 6. What is the smallest possible whole-number length for the third side?

c=4

Step-by-step explanation:

a=9, b=6, c=?

|a-b|<c<|a+b| (Triangle inequality)

|9-6|<c<|9+6|

|3|<c<|15|

3<c<15

then c=4 (smallest possible)

4

Step-by-step explanation:

Let the third side = x.

The sum of any two sides must be greater than the third side

9+6 > x

15 > x

9 + x > 6

x > 6-9

x > -3

6+ x > 9

x > 9-6

x > 3

So 3 < x < 15

Therefore the smallest whole number length the third side could have is 4.

The largest whole number length the third side could  have is 14.

step-by-step explanation:

yuo ned the activity or vertical angle of the form of 1,7 but 2,2 has a c4,2 as it verticie so i not have a car

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
