The lengths of two sides of a triangle are 19 cm and 26 cm. Write an inequality that represents the range of
possible lengths for the third side.

it matters what kind of triangle it is

Step-by-step explanation:

Step-by-step explanation:

let the third side =x

x>26-19

or x>7

and x<26+19

x<45

so range is 7<x<45

26?

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
