WX←→−WX↔ and YZ←→YZ↔ intersect at point *V*. If m∠WVY=(4a+58)°m∠WVY=4a+58° and m∠XVY=(2b−18)°,m∠XVY=2b-18°, find the values of *a* and *b* such that WX←→−WX↔ is perpendicular to YZ←→.

Given that the lines \( WX \) and \( YZ \) intersect at point \( V \) and are perpendicular to each other, the angles formed by the intersection are right angles, i.e., \( \angle WVY \) and \( \angle XVY \) are \( 90^\circ \) each.

We are given:
- \( m\angle WVY = (4a + 58)^\circ \)
- \( m\angle XVY = (2b - 18)^\circ \)

Since the lines are perpendicular, we have:

\[
m\angle WVY = 90^\circ \quad \text{and} \quad m\angle XVY = 90^\circ
\]

### Step 1: Solve for \( a \)
Set \( m\angle WVY = 90^\circ \):

\[
4a + 58 = 90
\]

Subtract 58 from both sides:

\[
4a = 32
\]

Divide by 4:

\[
a = 8
\]

### Step 2: Solve for \( b \)
Set \( m\angle XVY = 90^\circ \):

\[
2b - 18 = 90
\]

Add 18 to both sides:

\[
2b = 108
\]

Divide by 2:

\[
b = 54
\]

### Conclusion:
The values of \( a \) and \( b \) are \( a = 8 \) and \( b = 54 \).
