Question

class work: monday 9/8/25

  1. a c b (ac=6x+2, cb=x+1, ab=52) x=__ ac=__
  2. if e lies between b and c then ____
  3. if d is in the interior of ∠abe then ____

(diagram: v, a, b, c; ∠avc=72°, ∠aub=5x+5, ∠bvc=8x+2) find x=__, m∠aub=, m∠bvc=__

Explanation:

Response
Problem 1: Segment Lengths

Step1: Set up the equation

Since \( AC + CB = AB \), we have \( (6x + 2) + (x + 1) = 52 \).
Simplify: \( 7x + 3 = 52 \).

Step2: Solve for \( x \)

Subtract 3 from both sides: \( 7x = 52 - 3 = 49 \).
Divide by 7: \( x = \frac{49}{7} = 7 \).

Step3: Find \( AC \)

Substitute \( x = 7 \) into \( AC = 6x + 2 \): \( AC = 6(7) + 2 = 42 + 2 = 44 \).

Brief Explanations

If \( E \) lies between \( B \) and \( C \), then by the segment addition postulate, \( BE + EC = BC \) (or \( BB + EC = BC \) if there's a typo, but likely \( BE + EC = BC \)).

Step1: Set up the angle equation

Since \( \angle AUB + \angle BVC = \angle AVC \), we have \( (5x + 5) + (8x + 2) = 72 \).
Simplify: \( 13x + 7 = 72 \).

Step2: Solve for \( x \)

Subtract 7: \( 13x = 72 - 7 = 65 \).
Divide by 13: \( x = \frac{65}{13} = 5 \).

Step3: Find \( m\angle AUB \)

Substitute \( x = 5 \): \( 5(5) + 5 = 25 + 5 = 30^\circ \).

Step4: Find \( m\angle BVC \)

Substitute \( x = 5 \): \( 8(5) + 2 = 40 + 2 = 42^\circ \).

Answer:

\( x = 7 \), \( AC = 44 \)
