Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ is the central angle formed at the center of the circle.
r represents the radius of the circle.
π represents a constant whose value is 3.14
From the information given,
r = 21 inches
θ = 25 degrees
Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,
∠4 = 90 (verticallyopposite)
∠2 = 68 (verticallyopposite)
∠6 = ∠2 + ∠4 (exterior angles = sum of opposite angles)
∠6 = 68 + 90 = 158°
Answer: 158°
If you mean the measure of angle A then the answer is 28°
2x + 7 = 3
2x = 3 - 7
2x = -5
x = -5/2
1/8 = 0.16/x...1 gal to 8 pts = 0.16 gal to x pints
cross multiply
(1)(x) = (8)(0.16)
x = 1.28 pints per second
1.28 * 25 = 32 pints are dispensed in 25 seconds
