Question 3

On the street map shown below, Elm Street and Oak Street meet at a right angle.

Which equation shows how to find the measure of the angle formed by Maple Street and Oak Street?

Accepted Answer

$90^\circ -50^\circ = 40^\circ$

Answer

$90^\circ + 50^\circ = 140^\circ$

Answer

$180^\circ + 50^\circ = 230^\circ$

Answer

$180^\circ -50^\circ = 130^\circ$
