**10. MULTIPLE CHOICE:** What is \( m\angle UVW \)?
A) 39
B) 42
C) 81
D) 138
**Diagram Explanation:**
The diagram shows three lines intersecting at point V. The lines are labeled U, V, and W, forming angles at point V.
- Line \(\overrightarrow{UV}\) and \(\overrightarrow{VW}\) form an angle of 39°.
- Line \(\overrightarrow{VW}\) extends in the opposite direction, forming a linear pair of angles.
- The angle on the opposite side of \(\angle UVW\) is marked as 138°.
To find \( m\angle UVW \), note that \(\angle UVW\) and the angle marked 138° are supplementary angles because they form a linear pair. Therefore, \( m\angle UVW = 180° - 138° = 42° \).
The correct answer is B) 42.

Transcribed Image Text:**Given**: \( k \parallel m \), find each of the following.
7. The value of \( x \).
8. The value of \( y \).
9. The measure of \(\angle 6\).
**Diagram Description**:
- Two parallel lines \( k \) and \( m \) are intersected by a transversal.
- There are four angles formed at the intersection.
- One angle is labeled \((5x - 7)^\circ\).
- Another angle is labeled \((4y + 3)^\circ\).
- A third angle is labeled \((3x + 17)^\circ\).
- The fourth angle, located below the transversal on the same side as the \((3x + 17)^\circ\) angle, is marked as \(\angle 6\).
