Hope this helps
Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
12 1/2 is 12.50 as a mixed number
Answer:
1.5
Step-by-step explanation:
Vertical angles are congruent so:
7x=8x-12
Subtract 7x from both sides:
0=8x-12
Add 12 to both sides:
8x=12
Divide both sides by 8:
x=1.5 or
x= 3/2
