How do you solve this?

The plane needs to be about 27 meters higher to clear the tower

Step-by-step 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

answer: the first graph

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
