Answer 2

Given rectangle TREC, diagonal ET = 34 units.

What are properties of diagonals of rectangle?

The diagonals of a rectangle are equal and bisect each other

In rectangle TREC, diagonal ET bisects diagonal RC.

2x - 3 = x + 7

x = 10

(2x - 3) + (x + 7) = RC

RC = 20 - 3 + 10 + 7 = 34 units

Since, Diagonal RC = Diagonal ET

ET =  34 units
