Question

Figure is triangle c is biggest side, a and b are same size
19.
In figure-4, compute c if a = 3 and b = 2.
20.
In figure-4, compute b assuming 27a= and c =2b. ()

Answer 1

We do not have figure-4.

Answer 2

19. If this is a rt triangle:

c^2 = a^2 + b^2 = 9 + 4 =13,
c = sqrt (13) = 3.61

20. 27a = ? Please clarify.
