If two sides of a triangle are 7 and 12, what are the possible values for the third side?

A triangle  ABC has 3 sides and they have to satisfy the following.

     | a - b |  <  c < (a+b) 

 length of a side must be less the sum of the other two and more than the difference between the other two.

Hence,  the third side,  has to be more than  (15-12) = 3 cm.   Also it has to be less than (15+12) = 27 cm.     It is in between  3 cm and 27 cm

7 or 12

Step-by-step explanation:

Since we're dealing with a triangle, there are two pairs of sides that are going to be equal to each other.

The left and right would be 7 by 7, and the top and bottom would be 12 by 12.

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
