Answer:
The plane needs to be about 27 meters higher to clear the tower
Explanation:
The plane is 42 meters away from the tower.The tower is 98 meters high. Applying the Pythagorean relationship where the tower height is b and the distance of plane from tower is a, after take off, the plane reaches a flight distance of 83 meters from the ground at an angle.Finding b
a²+b²=c²
42²+b²= 83²
b²=83²-42²
b²=5125
b=√5125
b=71.59 meters
After travelling 83 meters, the plane will have cleared about 72 meters of the tower.
The remaining meters to clear the height of tower is: 98-72= 27 meters
