Both of this angles are same side interior angles which means both of this angles when added equal to 180 degrees
5x +15 + 3x - 3 = 180
8x - 12 = 180
+12 +12
8x = 192
x = 24

Answer: 410 square km
Step-by-step explanation:
The area of each of the triangles with their base on the 10 km side is
, so their combined area is
.
The area of each of the triangles with their base on the 12 km side is
, so their combined area is
.
The area of the bottom rectangular face is
