Answer: 311.5
Step-by-step explanation: 35*8.9=311.5
311.5/35=8.9
First, we can simplify the left side. (6+8x)/2 is equal to 3 + 4x. We can put the equation together at this point.
3 + 4x = 5x
we can subtract 4x from both sides to get our final answer,
3 = x, or x = 3. :)
Vertex angle = x
1 base angle = 1/2x - 8
180-x = (1/2x-8)x2
180-x = x-16
196-x = x
196 = 2x
x=98
