Question

In the diagram below segment DEF is shown (since all three letters are shown, they are collinear). If

Answer 1

Answer:

• x = 4

Step-by-step explanation:

Given

• DE = 3x + 2, EF = x + 5, DF = 23

As per segment addition postulate

• DE + EF = DF

Substituting values:

• 3x + 2 + x + 5 = 23
• 4x + 7 = 23
• 4x = 16
• x = 4
