So according to angle sum property :
x + x + 56 = 180
2x + 56 = 180
x = 180 - 56 /2
x = 62°

Here's how you solve this problem.
1) find how many kilometers equals 1 mile (16/10=1.6).
2) Divide 100 (from 100 km/h) by 1.6 (1.6×100=62.5).
3) solve for mph.
The answer is 62.5mph.
Volume of triangular prism + volume of rectangular prism = total volume
16*4*6+1/2*12*9=V
438=V
The volume of the figure is 438ft²
