Answer:
48
Step-by-step explanation:
The sum of angles of a triangle is 180
<V + <P + <M = 180
47+85+x = 180
132 +x = 180
Subtract 132 from each side
132-132+x = 180-132
x =48

Answer:
V = 381 in³
Step-by-step explanation:
The figure is composed of a rectangular prism and a triangular prism.
The volume (V) of the complete figure is
V = volume of rectangular prism + volume of triangular prism
= (16 × 7 × 3 ) + ( 
× 3 × 5 × 6 )
= 336 + 45
= 381 in³
