Answer:
Step-by-step explanation:
Use the Law of Cosines to find the measure of angle A from the lengths of the sides.
A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°
B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°
C = 180 - A - B = 95.3°
A = 1
b = -1
a + b =
1 + (-1) =
1 - 1 =
0....so a + b = 0
additive inverse property states that every real number added to its additive inverse (or opposite) will equal zero.
