Answer:
x = 14.5
Step-by-step explanation:
Exterior angle thm
<C = <D
7x - 2 = 9x - 31
7x - 9x = -31 + 2
-2x = -29
x = 14.5

Answer:
bbbbbbbbbbbbbbbbbbbbbbbbbbbb
Step-by-step explanation:
If you are talking about the area and perimeter of one of the triangular faces...
8 x 1.2 = 9.6
6 x 1.2 = 7.2
Perimeter = 9.6 + 7.2 + 7.2 = 24
Area = Linear Scale Factor²
1.2² = 1.44
7 x 1.44 = 10.08 (units)²
