Answer:
a)
<u>Verify is the corresponding sides have same ratio:</u>
- AB / DE = 50/60 = 5/6
- BC / EF = 20/24 = 5/6
Since the ratios are same, the triangles are similar
b)
<u>If one dimension is same, the base areas will make difference by the square of the scale factor:</u>
According to the laws of logarithm:
if log ₐ c =b
then:
aᵇ=c
hence, to solve the question we let:
log₆1296=a
thus to solve the above we re-write as follows:
6ᵃ=1296
the answer is option D
