Andrea is a civil engineer designing a new rod. This new road will connect two intersecting roads and form a triangular piece of land. She has measured the angles , the roads need to meet at to form an oblique triangle. One intersection has a 54° angle, another intersection makes a 47° angle. The side across from the 54° angle, is 320 feet. Determine the length of the other two roads
Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
