We may draw a vertical that bisects the vertex angle and the shorter side of the triangle, to form a right-triangle with the measurements:
hypotenuse = 8
length = 1.5
We may then apply:
sin(∅) = P / H
sin(∅) = 1.5 / 8
∅ = 10.8 ≈ 11°
This is half of the vertex angle, so the vertex angle is:
11 * 2 = 22°

Answer:
%28.57 (14285714286)
Step-by-step explanation:
Divid To get decimal (percent right)
250/350= 0.714285714285714
Subtract from 1 to get decimal (Percent wrong)
1.0 - 0.714285714285714= 0.285714285714286
Move over decimal to placements to the right to convert to percent
%28.5714285714286
Round
%28.57
