Scale Factor = 3/2
6 X (3/2) = x-2
9 = x-2
x = 11
8 X (3/2) = y + 3
12 = y+3
y = 9
Answer:
A 161 square feet
Step-by-step explanation:
5×5=25
1/2 of 25 is 12.5(triangular face) ×2=25
5×8 is 40 (base and left face)
8×7 is 56 (right face)
25+40+40+56=161
Given:



To find:
The value of a and PQ.
Solution:
We have,

(CPCTC)
So,


Isolating variable terms, we get


Divide both sides by -2.


Now,




Therefore, the value of a is 8 and the value of PQ is 28.
