given δ r s t is similar to δ u v w with rt = 9 inches, uw = 5.4 inches, and rs = 6 inches.
which is the length of

u
v
?
a.
3.6 inches
b.
2.4 inches
c.
8.1 inches
d.
4 inches

Find the scale of the known sides:

RT is similar to UW

5.4 /9 = 0.6

The smaller triangle is 0.6 times the larger one.

Multiply the length of RS to find UV:

6 x 0.6 = 3.6

The answer is A. 3.6 inches.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
