The angle of elevation is the angle from the horizontal look

The angle of elevation is the angle from the horizontal looking up at an object The angle of elevation of an airplane is radians, nd the altitude of the plane is 13.000 ft. H far away is the plane s the crow flies\" which means through the air rather than on the ow ground? The airplane is ft away as the crow flies. (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression

Solution

sin theta=opposite /hypotenuse

sin pi/4=13000/hypotenuse

hypotenuse=13000/sin pi//4 = 13000/(1/sqrt2)=13000sqrt2 feet
