Question

In Fig. 14.31 do no 15 only ​

Answer 1

Answer:

Step-by-step explanation:

Given,

1. BE = BF

2. The given figure is a square

3. AB = (7t-6) and AD = (2t-9)

(a) AB = AD (because all sides in a square are equal)

  7t-6 = 2t-9

7t-2t  = -9+6

     5t = -3

      t = -3/5

(b) AB = 7t-6

           = 7(-3/5)-6

           = -21/5 -6

           = -10.2
