Answer 1

Problem

Solution

For this case we can see that < P= < T

So then we need to satisfy this:

1.8cm = 3z-3

And if we solve for z we got:

1.8 +3 = 3z

4.8 = 3z

z= 4.8/3= 1.6cm

Then the final answer for this case would be

z= 1.6cm

And the lenght of the side :

3(z-1) = 3* (1.6-1) = 1.8cm
