The segments shown below could form a triangle.
o
O A. True
C
B Fase

False

Step-by-step explanation:

The sum of the smaller two sides must be larger than the third side

8+7 > 15

15 >15

This is not true so the three sides cannot form a triangle

c

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
