Question

The attached image shows a Scalene Triangle. The measurements were taken from point A. Given the known degree and directions of various numbered points throughout the surrounding area of Point A, what is the distance between Point B and C? What is the degree? This is not a graded assignment; measurements were not taken between two homes.

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).

Follow-up Question

Thank you. If I am understanding this, without the degree from A to B; A to C, or C to B it would've been virtually impossible to conduct the calculations.

For example, the distance from 2 to 3 can be performed since we have a distance and degree to both 2 and 3 from A. In this example, how would I find the degree angle between two and three in order to use the lawof cosines?
