118 degrees is your answer... I am the type of person that just answers it without an explanation.
62 deg F = 16.66... deg C
-62 deg F = -52.2 deg C.
tan(62 deg) = 1.8807 approx.
Vertex angle = 180 - 2(62) = 56 degrees
Sin(62 deg) = 0.8829Sin(62 deg) = 0.8829Sin(62 deg) = 0.8829Sin(62 deg) = 0.8829

-62 deg F = -52.2 deg C.
Suppose the length of the shadow is s metres. Then tan(62 deg) = 45/S so that S = 45/tan(62 deg) = 45/1.88 (approx = 23.93 metres, approx.
sin(62 deg) = 0.8829
tan(62 deg) = 1.8807 approx.
180 - x + 90 - x = 146 124 = 2x x = 62
62
118 degree angle
Vertex angle = 180 - 2(62) = 56 degrees
Let its sides be a b c and their opposite angles be A B C and so:- Using the cosine rule angle A = 17.9 degrees Using the cosine rule angle B = 120 degrees Angle C: 180 -17.9 -120 = 42.1 degrees Area: 0.5*48*22*sin(120) = 457 square cm rounded
