Angle depression hot air balloon is floating above a straight road. to estimate their height above the ground, the balloonists simultaneously measure the angle of the depression to two consecutive milepost on the road on the same side of the balloon. the angles of depression are found to be 20 degree and 22 degree . how high is the balloon?

SOURCE: TRIANGLES

• FROM A WINDOW 30 feet above the ground,a building 100 feet high, and at a distance of 200 feet, is observed.find the angle of elevation of the top of the building and the angle of depression of its base.

SOURCE: distance from the building 200 ft. angle of elevation 60 degrees

Depends ur height and building's height

SOURCE: angle of alevation

height =50
length = 60
angle=x

tangent(x)=50/60
tangent(x)=0.833
x=39.8 degree

SOURCE: Angle of elevation

11.3628 M

SOURCE: An airplane is flying at a height of 2 miles above

a2+b2=c2
a being your height, b is your distance from the airport and c is the distance from the airport to the plane........ so the answer is 5.385164807134504 miles
