Question

Assume each pair of figures, the second polygon is similar to the first, with the same orientation.

Answer 1

5.

6 / t = 9 / (t+2)

9t = 6t + 12

3t = 12

t = 4   answer

The remaining length:-

6 / 4 = 11 / x

6x = 44 so x = 7.33  answer

6.  8 / w = 6 / (w - 5)

6w = 8w - 40

2w = 40 so w = 20 answer

The side marked w - 5  = 20-5 = 15 answer

8/14 = 20/x giving the top side =  35  answer
