Find the lengths of a and b.
a: a=10 ft, b=10 ft
b: a= 5 square root 2 ft, b= 10 ft
c: a= 20 ft , b= 20 ft
d: a= 5 square root 2 ft , b= 5 square root 2 ft

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.

thus, the first answer choice, y = sec x, is the correct one
