Answer:
0.50 (still the same)
Step-by-step explanation:
To find the area of a prism, you calculate the area of the cross-section and multiply that number by the length. The cross-section of this prism is a trapezium, and the formula for this is

.
Insert your given numbers to find out the area of this prism's cross-section:

Now, multiply 90 by the length, 10cm, to find out the volume of the prism;
90×10=900cm³
Therefore, your answer id the third option.
The bases of triangles are paralleles, so the angles are the same, the sum og the interior angles are always 180° in a triangle, so 180 - 55 -60 = 65°
x = 65°
y = 60°
z = 55°
