Answer:
Each piece is 2 ft and 8 inches long.
Explanation:
12 inches are in a foot, so 12 times 8 equals 96.You then divide 96 by 3 which is 32.So 32 inches is 12in+12in+8in= 2feet 8 inches
A² + b² = c² ⇒ right triangle
a² + b² < c² ⇒ obtuse triangle
a² + b² > c² ⇒ acute triangle
a = 12 ft ; b = 15 ft ; c = 20 ft
12² + 15² = < > 20²
144 + 225 = < > 400
369 < 400 OBTUSE TRIANGLE
√369 = 19.21
20 - 19.21 = 0.79
<span>It is an obtuse triangle. About 0.8 foot needs to be removed from the 20-foot board to create a right triangle.</span>
