Answer:
160 m
Step-by-step explanation:
For the 15-deg angle, h is the opposite leg.
The hypotenuse is 628 m.
The trigonometry ratio that relates the opposite leg and the hypotenuse is the sine.
sin A = opp/hyp
[tex] \sin 15^\circ = \dfrac{h}{628~m} [/tex]
[tex] h = 628~m \times \sin 15^\circ [/tex]
[tex] h = 162.54~m [/tex]
Rounded to 2 significant figures:
h = 160 m
