Know the Answer?

Ryann Diaz · Answer 1

So we have

the angle is 35 °

the adjacent side is 660

height or elivation or oposite side is h

what trig equation relates oposite and adjacent?

tan

tanx=o/a

tan35 °=h/660

times 660 both sides

660tan35 °=h

evaluate

462.137ft aprox

do not use sin or cos because they relate hypotnuse which is the distance to the hawk, not the height of the hawk
