Step-by-step explanation:
De+eF=DF
3+eF=15
eF=15-3
eF=12
Answer:
c
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given: AB≅DE, BC≅EF, CA≅FD
Since those are the given it is maped A to D, B to E, C to F
This is a rigid transformation because the distance is preserve (givens) and the triangle ABC is map to triangle DEF.
Rigid transformations produce congruent figures so triangle ABC is congruent to triangle DEF
Answer:
The height of the trapezoidal base is 7.2 ft.
Step-by-step explanation:
Consider the provided information.
The volume of trapezoidal prism is the area of the cross-section × the length.

Where B is the area of base, H is the length and V is the volume.
The length of the prism is 25.2ft and volume is 1279.152


Hence, the base area is 50.76 ft².
The base is trapezoid.
The area of trapezoid is 
Substitute B=50.76,
in above formula.



Hence, the height of the trapezoidal base is 7.2 ft.
