All of the above. it is a three dimensional pyramid, and a "polyhedron" means it is triangular.
Answer:
The answer to your question is: x = 115.5 in
Step-by-step explanation:
Data
Student's height = 5 ft 3 in = 63 in
Student's shadow = 4 ft 6 in = 54 in
Sculpture's shadow = 8 ft 3 in = 99 in
Sculpture's height = ?
Process
Thales' theorem
63 in/54 in = x/99
x = 99 x 63 / 54
x = 115.5 in
Answer: 4 and 8
Step-by-step explanation:
1. 12+7x=40
7x=28
x=4
2. 6x-3=45
6x=48
x=8
I think the answer is the last one
Answer:
C 14
Step-by-step explanation:
7 ×4 ×1/2=14
because triangle area formula is A=1/2×B×H
B= base
H= height
