Answer:
h = 160 m
Explanation:
h is the length of a leg. h is opposite the 15-deg angle.
The hypotenuse measures 628 m.
The since is the trig ratio that relates the opposite leg to the hypotenuse.
sin A = opp/hyp
sin 15 deg = h / 628 m
h = 628 m * sin 15 deg
h = 628 m * 0.2588
h = 162.54 m
Rounded off to two significant digits, the answer is
h = 160 m
