Answer:
The angle F = 47.25°
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that f =42inches and e = 39 inches
Given that ∠E = 43°
By using sine rule
⇒ 
Cross multiplication , we get
⇒ 39 sin F = 42 × sin 43°
⇒ sin F = 0.734459
<u><em>Step(ii):-</em></u>
⇒ sin⁻¹ (sin F)= sin ⁻¹ ( 0.734459)
⇒ F = 47.25
The angle F = 47.25°

P(x) = (-0.32x² + 270x) - (70x + 52)
P(x) = -0.32x² +270x -70x -52 . . . . . . . . eliminate parentheses
P(x) = -0.32x² +200x -52
.19 seconds
This is because 12.38-12.19= .19
