Answer:
The altitude is changing at a speed of 200 √3 km/hr
Step-by-step explanation:
Here, we want to know how far the altitude of the plane is changing
we are told that the airplane makes an angle of 60 degrees with the ground
So therefore , the rate of change of its altitude will be ;
sin 60 = x/ 400
x = 400 sin 60
x = 400 * √3/2
x = 200 √3 km/hr
Answer:
It's 70°
Step-by-step explanation:
∠APB = ∠RPQ = 35°
Now, ∠AOB and ∠APB are angles subtended by an arc AB at centre and at the remaining part of the circle .
∴∠AOB = 2∠APB = 2 × 35° = 70°
I think it might be 18 sorry if im wrong
