Answer:
2/7.
Step--step explanation:
1/2 * 4/7.
Multiply the numerators and the denominators:
= 1*4 / 2*7
= 4 / 14 Now divide numerator and denominator by 2:
= 2/7.
Answer:could you maybe simplify the question
Step-by-step explanation:
Answer:
6 inches
Step-by-step explanation:
Area = (base1 + base2)/2 · height
base1 = b
base2= 8
height = 3
Area = 21
21 = (b+8)/2 ·3
21 = 3(b+8)/2
multiply both sides by 2
42 = 3(b+8)
divide both sides by 3
14 = b+8
subtract 8 from both sides
b = 6 in

Each Exterior Angle = Each Central Angle = (360 degrees) ÷ (Number of Sides)
</span>Each Exterior Angle = <span>(360 degrees) ÷ (Number of Sides)
</span><span>(Number of Sides) = 360 / 36
</span><span>Number of Sides = 10
a 10-sided polygon is a decagon
