Answer:
x = 20
Step-by-step explanation:
The congruence statement tells you that angle A is congruent to angle D. (Both are listed first in the triangle names.) This means ...
∠A = ∠D
3x -10 = 2x +10
x = 20 . . . . . . . . . . add 10-2x to both sides

v=1/2(13.1+25.4)(17)(15)
v=1/2(38.5)(255)
v=4,908.7 ft³
