Answer:
x = 1
Step-by-step explanation:
Given
8x - 2(x - 7) = 20 ← distribute parenthesis on left side
8x - 2x + 14 = 20, that is
6x + 14 = 20 ( subtract 14 from both sides )
6x = 6 ( divide both sides by 6 )
x = 1
The number of triangles is n-2
n= number of sides
8-2= 6 triangles
if applying this you won't have to draw any diagonals to
find the number of triangles just subtract 2 from the number of sides
hope this helps
