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°
