Answer:
9.936
Step-by-step explanation:
V = Bh
B = base
base = Lengh x width
base = 4.8 x 2.3
base = 11.04
V = 11.04h
H = height
H = .9
V = .9 x 11.04
V = 9.936

The sum of the 3 angles in a triangle = 180°, that is
∠ 1 + ∠ 2 + ∠ 3 = 180°
Given ∠ 1 + ∠ 2 = 134°, then
134° + ∠ 3 = 180° ( subtract 134° from 180° )
∠ 3 = 46° → D
