Answer:
A = 38°
Step-by-step explanation:
We are going to use cosine law to find angle A where
a = 4.7
b = 3.9 m
c = 2.9 m
or
cos A = [(4.7)^2 + (3.9)^2 - (2.9)^2]/2(4.7)(3.9)
= 28.89/36.66
= 0.788
A = arccos(0.788) = 38°
(2, 2)
Points B and C are symmetric (Divided by the y axis) so that means we have to find the mirrored version of A that is divided by thee y axis which is (2, 2)
131.3312, and if rounded 131
