Answer:
Step-by-step explanation:
Let the speed of plane is p and speed of the wind is w.
<u>Then we have:</u>
- 10*(p + w) = 1120 ⇒ p + w = 112
- 20*(p - w) = 1120 ⇒ p - w = 56
<u>Sum the two equations and solve for p:</u>
- p + w + p - w = 112 + 56
- 2p = 168
- p = 84
<u>Find w:</u>
- 84 + w = 112
- w = 112 - 84
- w = 28

Answer:
8
Step-by-step explanation:
Using sine rule,
sin 80° ÷ 10 = sin 50° ÷ x
x = sin 50° ÷ (sin 80° ÷ 10)
= 7.77 --> 8
