Answer:

PQ = 1

PR = RQ

PR = RQ = 2.3

Explanation:

PR = RQ

The marks on sides PR and RQ means that the two sides are congruent and thus, they're equal.

Therefore, we can find x by setting the expression representing side PR (3x - 0.4) equal to the expression representing side RQ (x + 1.4):

3x - 0.4 = x + 1.4

3x = x + 1.8

2x = 1.8

x = 0.9

PQ = 1:

We can see that PQ = 1 by plugging in 0.9 for x in the expression representing side PQ:

PQ = 0.9 + 0.1

PQ = 1

PR = RQ = 2.3

We can see that both PR and RQ = 2.3 by plugging in 0.9 for x in the two expressions representing PR and RQ:

PR = 3(0.9) - 0.4

PR = 2.7 - 0.4

PR = 2.4

RQ = 0.9 + 1.4

RQ =2.3
