Question

43 what is the measure of the angle formed by park street and oak street? 90° 45° 35° 55°

Explanation:

Step1: Identify vertical - angle relationship

Vertical angles are equal. The angle adjacent to the angle formed by Park Street and Oak Street is a vertical angle to the given $35^{\circ}$ angle.

Step2: Determine the angle measure

Since vertical angles are equal, the angle adjacent to the angle between Park Street and Oak Street is $35^{\circ}$. And since the angle between Park Street and Oak Street and this adjacent angle are complementary (as the lines are perpendicular - indicated by the right - angle symbol), the angle between Park Street and Oak Street is $90^{\circ}-35^{\circ}=55^{\circ}$.

Answer:

$55^{\circ}$
